Published: June 2016

AbstractNickel–iron oxides and oxyhydroxides are among the most active oxygen‐evolution reaction (OER) catalysts in alkaline electrolytes. Compositions rich in Ni are reported to show superior activity, but the establishment of competitive OER activity with lower cost, Fe‐rich analogues is more desirable for metal–air batteries and other devices that will see large‐scale production. Herein, we demonstrate that by controlling pore–solid architecture and the degree of crystallinity, we achieve a single‐phase, Fe‐rich NiFe2Ox catalyst that matches the OER performance metrics previously demonstrated for compositions with higher Ni‐to‐Fe ratios. We also show that OER activity linearly tracks increases in the catalyst surface area, whereas the degree of ex situ surface hydroxylation does not play a significant role. To prepare the pore–solid structured forms, NiFe2Ox gels were synthesized by using an epoxide‐initiated sol–gel method and subsequently processed to aerogels or xerogels. The activities of these two sol–gel‐derived nanostructures were compared with a nanoparticulate analogue with lower specific surface area, prepared by using conventional precipitation methods. The higher surface area and larger pore volume expressed by the NiFe2Ox formed as an aerogel result in a performance‐competitive OER overpotential of 356 mV at a current density of 10 mA cm−2, with an approximately 140 mV improvement relative to the low‐surface‐area, precipitated analogue.

Published: June 2016

AbstractA self‐supporting film composed of arrays of Li4Ti5O12 (LTO) nanoparticles (NPs) prepared through chemical lithiation of anodic TiO2 nanotube arrays and calcination in air is used as a high‐performance binder‐free anode in lithium‐ion batteries (LIBs). The LTO nanoparticles formed in situ are closely connected along the axial direction of the pristine TiO2 nanotubes, forming a beaded stream‐like structure. The self‐supporting NPs film has a large tap density and overall packing factor, and the three‐dimensional (3D) network of NPs increases the electroactive interface, facilitating transfer of Li+ and enhancing the intercalation kinetics during charging/discharging. The LTO electrode with excellent mechanical flexibility and robustness has a volumetric capacity of 304 mAh cm−3 at a current density of 50 mA cm−3 as well as a high rate capability of 208 mAh cm−3 at 5000 mA cm−3. After undergoing 500 cycles at a high current density of 1250 mA cm−3, 91.4 % of the capacity is retained, demonstrating high reversibility and cycling stability of the binder‐free LTO NPs film electrode in LIBs.

Published: June 2016

AbstractA 3D metal–organic framework (MOF) having single‐molecule magnet (SMM) linkers was prepared in crystalline form by using a tetrairon(III) complex functionalised with two divergent pyridyl groups, namely [Fe4(pPy)2(dpm)6] (1; H3pPy=2‐(hydroxymethyl)‐2‐(pyridin‐4‐yl)propane‐1,3‐diol, Hdpm=dipivaloylmethane). Reaction of 1 with silver(I) perchlorate afforded {[Fe4(pPy)2(dpm)6]2Ag}ClO4 (2), which crystallises in a cubic face‐centred lattice and exhibits two interlocked diamondoid networks. In 2, the SMMs act as linear ditopic synthons, and silver(I) ions as tetrahedral nodes coordinated by four pyridyl nitrogen atoms. The magnetic properties of 1 (S=5 and D≈−0.4 cm−1 in the ground spin state) are largely preserved in 2, which shows slow magnetic relaxation with an anisotropy barrier of Ueff/kB=11.46(10) K in zero field and 14.25(8) K in an applied field of 1 kOe. However, crystal symmetry triggers highly noncollinear magnetic anisotropy contributions oriented at 109.47° from each other along the threefold axes of AgN4 tetrahedra, a unique scenario fully confirmed by a single‐crystal cantilever torque magnetometry investigation. Magnetisation curves down to 0.03 K demonstrated the occurrence of a wide hysteresis loop when the magnetic field was swept along one of the four Ag−N bonds. By symmetry, the crystalline compound can then be persistently magnetised parallel or antiparallel to the four main diagonals of the unit cell, although the crystals have no overall second‐order anisotropy.
An Ethylene‐Bridged Phosphane/Borane Frustrated Lewis Pair Featuring the ‐B(Fxyl)2 Lewis Acid Component

Published: June 2016

AbstractHydroboration of dimesitylvinylphosphane with bis[3,5‐bis(trifluoromethyl)phenyl]borane [HB(Fxyl)2] gave the intramolecular ethylene‐bridged P/B frustrated Lewis pair (FLP) Mes2PCH2CH2B(Fxyl)2. The new compound underwent a variety of typical FLP reactions such as P/B‐addition to the carbonyl group of p‐chloro‐benzaldehyde. Cooperative N,N‐addition to nitric oxide gave the respective persistent P/B FLPNO. radical, which readily reacted with 1,4‐cyclohexadiene by H‐atom abstraction to yield the corresponding P/B FLPNOH product. The B(Fxyl)2‐containing FLP reacted as a template for the HB(C6F5)2 reduction of carbon monoxide to the formyl stage to give the respective FLP(η2‐formylborane) product. Most products were characterized by single‐crystal X‐ray crystal structure analysis.
Surprisingly Different Reaction Behavior of Alkali and Alkaline Earth Metal Bis(trimethylsilyl)amides toward Bulky N‐(2‐Pyridylethyl)‐N′‐(2,6‐diisopropylphenyl)pivalamidine

Published: June 2016

AbstractN‐(2,6‐Diisopropylphenyl)‐N′‐(2‐pyridylethyl)pivalamidine (Dipp‐N=C(tBu)‐N(H)‐C2H4‐Py) (1), reacts with metalation reagents of lithium, magnesium, calcium, and strontium to give the corresponding pivalamidinates [(tmeda)Li{Dipp‐N=C(tBu)‐N‐C2H4‐Py}] (6), [Mg{Dipp‐N=C(tBu)‐N‐C2H4‐Py}2] (3), and heteroleptic [{(Me3Si)2N}Ae{Dipp‐N=C(tBu)‐N‐C2H4‐Py}], with Ae being Ca (2 a) and Sr (2 b). In contrast to this straightforward deprotonation of the amidine units, the reaction of 1 with the bis(trimethylsilyl)amides of sodium or potassium unexpectedly leads to a β‐metalation and an immediate deamidation reaction yielding [(thf)2Na{Dipp‐N=C(tBu)‐N(H)}] (4 a) or [(thf)2K{Dipp‐N=C(tBu)‐N(H)}] (4 b), respectively, as well as 2‐vinylpyridine in both cases. The lithium derivative shows a similar reaction behavior to the alkaline earth metal congeners, underlining the diagonal relationship in the periodic table. Protonation of 4 a or the metathesis reaction of 4 b with CaI2 in tetrahydrofuran yields N‐(2,6‐diisopropylphenyl)pivalamidine (Dipp‐N=C(tBu)‐NH2) (5), or [(thf)4Ca{Dipp‐N=C(tBu)‐N(H)}2] (7), respectively. The reaction of AN(SiMe3)2 (A=Na, K) with less bulky formamidine Dipp‐N=C(H)‐N(H)‐C2H4‐Py (8) leads to deprotonation of the amidine functionality, and [(thf)Na{Dipp‐N=C(H)‐N‐C2H4‐Py}]2 (9 a) or [(thf)K{Dipp‐N=C(H)‐N‐C2H4‐Py}]2 (9 b), respectively, are isolated as dinuclear complexes. From these experiments it is obvious, that β‐metalation/deamidation of N‐(2‐pyridylethyl)amidines requires bases with soft metal ions and also steric pressure. The isomeric forms of all compounds are verified by single‐crystal X‐ray structure analysis and are maintained in solution.

Stereochemical Properties of Multidentate Nitrogen Donor Ligands and Their Copper Complexes by Electronic CD and DFT
Authors: Poopari Mohammad Reza , Dezhahang Zahra , Xu Yunjie 
Published: June 2016

AbstractUV–Vis and electronic circular dichroism (ECD) spectroscopy, complemented with Density Functional Theory (DFT) calculations, were used to elucidate the structural diversities of three multidentate nitrogen donor ligands and two associated copper complexes in solution directly. The three chiral salen ligands all consist of trans‐cyclohexane‐1,2‐diamine as a chiral scaffold and also of pyridine rings as chromophores, differing only in the linking groups between the two functional groups mentioned above. Very different ECD intensities and somewhat different ECD patterns were observed for these ligands and satisfactorily interpreted theoretically. For the geometry optimization and spectral simulation of the open‐shell metal complexes, the LANL2DZ basis set with effective core potential for the Cu and Cl atoms and pure cc‐pVTZ for the rest of the atoms was utilized. The performance of the same calculations with the polarization functions (f,g) from the cc‐pVTZ basis added to the LANL2DZ basis was compared. While the three ligands exhibit different conformational flexibility, the associated copper complexes show great rigidity imposed by the metal–ligand coordination, taking on a single structure in each case. In addition, dispersion interactions were shown to change the conformational stability ordering of the ligands noticeably and to exert considerable influence on the simulated UV–Vis and ECD spectra.
