Abstract
We have determined the crystal and molecular structure of trans-bis(acetonitrile)dichloroplatinum(II). Crystallographic data for trans-Pt(CH3CN)2Cl2: monoclinic, space group P21/c, a = 5.0453(9), b = 6.9896(5), c = 11.962(1) Å , β = 101.40(1)°, V = 413.5 Å3, Z = 2 ,Dx = 2.796 g cm-3,μ(CuKα) = 377.5 cm-1, R = 0.0502, wR = 0.0529 for 43 variables and 807 reflections with F > 3σ(F). The Pt atom is in a planar configuration with N and Cl atoms in trans positions. The shortest distance between two Pt atoms corresponds to the length of the crystallographic a-axis (5.045 Å). Additionally, we present optical absorption data of the cis-and trans-isomer.

Abstract
N-M ethyl-2-dimethylaluminium pyrrolide, (CH3)2Al -C4H3NCH3, crystallizes in the triclinic space group P1̄ with the lattice constants a = 700.5(1), b = 725.9(1), c = 886.8(1) pm, α = 67.69(1)°, β = 70.99(1)°, γ = 88.48(1)°, and Z = 2. This compound is isotypic with the gallium homologue [1], the shortest metal-ring contact between the two molecules of one unit cell decreases to 228.6 pm. N-dimethylgallium tetramethylpyrrolide has been synthesized from Li-N (CCH3)4 and (CH3)2GaCl. This “π-associate” crystallizes in the monoclinic space group P21/c with the lattice parameters a = 989.9(2), b = 1305.4(3), c = 878.3(2) pm, β - 112.73(1)° and 4 units per cell. Again two centrosymmetrically orientated molecules form a dimer by short (224.0 pm) intermolecular “Ga - πC ” contacts but the structure differs significant from the structure of the indium homologue [1].

Template 1:1 condensation of 3,5-diacetyl-1,2,4-triazole with thiocarbohydrazide or car- bohydrazide in the presence of 1 equivalent of Pb(SCN)2 produces mononuclear [2 + 1] com­plexes 1 and 3. The analogous reaction with thiosemicarbazide and semicarbazide produces the dinuclear [1+2] complex 2 and the mononuclear metal free 4. The carbohydrazide deriva­tive 3 reacts with the carbohydrazide or the 1,3-diaminopropane to yield the macrocyclic dinuclear complexes 5 and 6.
Direct reaction of 3,5-diacetyl-1,2,4-triazole with thiocarbohydrazide. carbohydrazide, thiosemicarbazide and semicarbazide leads to open [1+1] ligands L1, L2, L3, L4, and closed [1+1] ligands (mesocyclic ligands) L5 and L6 were prepared by addition of 1 equivalent of LiOH to the reaction mixture.
The reaction of open and mesocyclic [1+1] ligands with copper(II) salts gives [CuLX2] and [Cu2+L2-] complexes. All these compounds have been characterized by 1H NMR, IR, electronic and mass spectra and by analytical data.

Abstract
The bipyridyldiacetylene 6,6′-(CH3CH2CH2C = C)2bpy (1) was prepared by palladium catalyzed C - C - coupling reaction of 6,6′-dibromo-2,2′-bipyridine with pentyne. Reaction of 1 with anhydrous CuCl2 in acetonitrile gave the dimeric, chloro-bridged complex (1)Cu(Cl)(µ-Cl)2Cu(Cl)(1) (2), which was characterized by X-ray crystallography. The copper atoms in 2 are square-pyramidally coordinated with normal in-plane Cu - N and Cu - Cl bond distances and one longer, apical bond to the second bipyridyl nitrogen atom. The influence of steric hindrance of the bipyridyl 6,6′-substituents on the structure of the complex is discussed.

Abstract
If for a given system two-dimensional (2D) 119Sn/1H heteronuclear shift correlations can be established for long range coupling constants nJ(119Sn,1H) (n = 4, 6), absolute signs of coupling constants J(Sn,Sn) are accessible by this technique for the first time. This has been demonstrated for tetrakis(trimethylstannyl)allene (1) with 2J(119Sn,117Sn) (>0) and 4J(Sn. 117Sn) (<0) and for tris(trimethylstannyl)phosphane (2) and bis(trimethvlstannyl)- sulfane (3) with 2J(119Sn,117Sn) (<0).

Isonitroso-(4-methylthiazol-2-yl)acetamide H (L1), isonitroso-(4-methylthiazol-2-yl)(benzo-thiazol-2-yl)methanide H(L2) and their copper(II) complexes of composition [Cu(Phen){L1}(ClO4)] (1) and [Cu(Phen){L2}Cl]*C2H5OH (2) have been prepared. Crystal and molecular structures of the complexes have been determined from X-ray diffractioon data (1: monoclinic, space group P21/c, with a = 11.611(2), b = 10.259(2), c = 17.869(4) Å, β = 104.67(3)°, V = 2059.1(7) Å3, Z = 4; R1 = 0.046 for the 2522 unique reflections with I > 2σ(I). 2: triclinic, space group P1̄, with a = 8.351(1), b = 10.876(1), c = 14.891(2) Å, a = 96.170(8)°, β = 94.201(9)°, γ = 106.721(9)°, V = 1280.1(2) Å3, Z = 2; R1 = 0.034 for the 4038 unique reflections with I > 2σ(I)). In the structure of 1 the coordination polyhedron of Cu2+ is a distorted square pyramid with an oxygen atom of the CIO4 counter anion in the apex (C u -O 2.505(3) Å); in complex 2 the copper atom adopts fivefold coordination of a slightly distorted trigonal-bipyramidal geometry with a chlorine atom in the equatorial plane (Cu-Cl 2.3504(9) A). Ethanol of crystallization gives rise to a hydrogen bond at the chlorine atom. In both structures the oximic anions are coordinated to the metal center in a bidentate chelate manner via the nitrogen atom of the nitroso group and the carbonyl oxygen atom (1) or via the benzothiazole nitrogen atom (2) (Cu-O, Cu-N in the range 1.963(2) -2.031 (2) Å). The thiazole group of the ligands takes no part in the coordination. The nitroso oxygen atoms possess short intramolecular contacts with thiazole sulphur atoms, with d(S--- O) at 2.605(3) (1) and 2.676(3) A (2), which may be attributed to a strong intraligand interaction.

Authors: Ali Muhammad Shaiq , Kitazume Tomoya , Ahmad Viqar Uddin 
Published: February 2015

Abstract
A fluorinated substrate 6 was prepared and then the enantiomers (6a and 7a) were separated by an enzyme in presence of an acetylating agent. The optical purity of 6a and 7a were determined by derivatising them into their MTPA -esters and then by taking their 19F NMR spectra. It was observed that, PL 266 (enzyme), benzene (solvent), 24 h (time), 40 °C (temp.) and vinyl acetate (acetylating agent) were the ideal conditions for racemic resolution. The optical purity was further improved by changing the solvent (hexane), amount of enzyme (PL 266; 3000 units), reaction time (12 h) and amount of acetylating agent (vinyl acetate; two molar). The optically pure species was used for the preparation of E and Z alkenes.

Reaction of 4N-methyl-2-[1-(pyrrol-2-yl)methylidene]hydrazinecarbothioamide (4ML1 and 4N-methyl-2-[1-(pyrrol-2-yl)-ethylidene]hydrazine carbothioamide (4ML1) with zinc(II), cadmium(II) and mercury(II) halides afforded complexes with formulas [M(L)X2] [(L; M; X) =(4ML1; Cd; Cl) (4), (4ML1; Hg; Cl, Br, I) (7 - 9), (4ML2; Cd; Cl) (17), (4ML2; Hg; Cl, Br, I) (20 - 22)] or [M(L)2X2] [(L; M; X) = (4ML1; Zn; Cl, Br, I) (1 - 3), (4ML1; Cd; Br, I) (5, 6), (4ML2; Zn; Cl, Br, I) (14 - 16), (4ML2; Cd; Br, I) (18, 19)]. Reaction of 4ML1 with salts of copper(II), nickel(II), palladium(II) and platinum(II) afforded complexes of formula [M(4ML1-H)2] (10 -13). Crystals of 11, 12 and 19 were studied by X-ray diffractometry, and all new compounds were characterized by elemental analysis, mass spectrometry, and IR, electronic and 1H and 13C NMR spectroscopy and, when pertinent and allowed by the solubility of the compound, 113Cd or 199Hg NMR spectroscopy. In the complexes of Group 12 metals, both ligands are neutral and S-monodentate. In the complexes of copper or Group 10 metals, 4ML1 is monodeprotonated and S,N-bidentate.
