Ferromagnetic Interaction in an Asymmetric End‐to‐End Azido Double‐Bridged Copper(II) Dinuclear Complex: A Combined Structure, Magnetic, Polarized Neutron Diffraction and Theoretical Study

Published: February 2007

AbstractA new end‐to‐end azido double‐bridged copper(II) complex [Cu2L2(N3)2] (1) was synthesized and characterized (L=1,1,1‐trifluoro‐7‐(dimethylamino)‐4‐methyl‐5‐aza‐3‐hepten‐2‐onato). Despite the rather long CuCu distance (5.105(1) Å), the magnetic interaction is ferromagnetic with J= +16 cm−1 (H=−JS1S2), a value that has been confirmed by DFT and high‐level correlated ab initio calculations. The spin distribution was studied by using the results from polarized neutron diffraction. This is the first such study on an end‐to‐end system. The experimental spin density was found to be localized mainly on the copper(II) ions, with a small degree of delocalization on the ligand (L) and terminal azido nitrogens. There was zero delocalization on the central nitrogen, in agreement with DFT calculations. Such a picture corresponds to an important contribution of the d orbital and a small population of the d orbital, in agreement with our calculations. Based on a correlated wavefunction analysis, the ferromagnetic behavior results from a dominant double spin polarization contribution and vanishingly small ionic forms.

Published: February 2007

AbstractA new efficient and safe synthesis of 3,3′‐dimethyl‐5,5′‐bis‐(1,2,4‐triazine) is presented. The electron‐density distribution and electrostatic properties (charge, electrostatic potential) of this molecule were analyzed. These properties were derived from a high‐resolution single‐crystal X‐ray diffraction experiment at 100 K and compared to the results obtained from ab initio DFT quantum‐mechanical calculations. Comparisons of its electrostatic potential features and integrated atomic charges (quantum theory of atoms in molecules, QTAIM) have been made with those of related molecules such as bipyrimidine ligands. Two methods were used to derive integrated charges: one is based on the conventional analytical procedure and the second uses a steepest‐ascent numerical algorithm. Excellent agreement was obtained between these two methods. Charges and electrostatic potential were used as predictive indices of metal chelation and discussed in the light of complexation abilities of the title compound and related molecules. The crystal structure of a CuIcomplex of 3,3′‐dimethyl‐5,5′‐bis(1,2,4‐triazine) is reported here. In the solid state, this complex forms a three‐dimensional multibranch network with open channels in which counterions and solvent molecules are located. This architecture involves bothcisandtransisomers of the title compound.

Multireference Calculation of the Photodissociation of Benzyl Chloride
Authors: Cao Jun , Liu Ya‐Jun , Fang Wei‐Hai 
Published: February 2007

AbstractThe photodissociation mechanism of benzyl chloride (BzCl) under 248 nm has been investigated by the complete active space SCF (CASSCF) method by calculating the geometries of the ground (S0) and lower excited states, the vertical (Tv) and adiabatic (T0) excitation energies of the lower states, and the dissociation reaction pathways on the potential energy surfaces (PES) of S1, T1 and T2 states. The calculated results clearly elucidated the photodissociation mechanism of BzCl, and indicated that the photodissociation on the PES of T1 state is the most favorable.
Relationship between Scattered Photon Counts and Concentrations of Some Saline Solutions in Compton Scattering
Authors: Luo Guang , Zhou Shang‐Qi , Han Zhong , Chen Shuang‐Kou 
Published: February 2007

AbstractCompton scattering saline solution was researched. Firstly according to the Compton scattering theory the linear relationship between the concentration and the scattered photon counts was obtained. And then it was proved by Compton scattering experiments for some solutions. According to those experiments, it was found that the slope was decreased when the atomic number of the cation was increased for alkali metal chloride solutions and alkaline‐earth metal chloride solutions. Based on those relationships, a new method was promoted with which to measure the concentration of saline solution untouched the measured solution.
New Amphiphilic Polypyridyl Ruthenium(II) Sensitizer and Its Application in Dye‐Sensitized Solar Cells
Authors: Kong Fan‐Tai , Dai Song‐Yuan , Wang Kong‐Jia 
Published: February 2007

AbstractAmphiphilic polypyridyl ruthenium(II) complex cis‐di(isothiocyanato)(4,4′‐di‐tert‐butyl‐2,2′‐bipyridyl)(4,4′‐ dicarboxy‐2,2′‐bipyridyl)ruthenium(II) (K005) has been synthesized and characterized by cyclic voltammetry, 1H NMR, UV‐Vis, and FT‐IR spectroscopies. The sensitizer sensitizes TiO2 over a notably broad spectral range due to its intense metal‐to‐ligand charge‐transfer (MLCT) bands at 537 and 418 nm. The photophysical and photochemical studies of K005 were contrasted with those of cis‐Ru(dcbpy)2(NCS)2, known as the N3 dye, and the amphiphilic ruthenium(II) dye Z907. A reversible couple at E1/2=0.725 V vs. saturated calomel electrode (SCE) with a separation of 0.08 V between the anodic and cathodic peaks, was observed due to the RuII/III couple by cyclic voltammetry. Furthermore, this amphiphilic ruthenium complex was successfully used as sensitizers for dye‐sensitized solar cells with the efficiency of 3.72% at the 100 mW·cm−2 irradiance of air mass 1.5 simulated sunlight without optimization of TiO2 films and the electrolyte.
