Copper (II), nickel (II) and vanadyl complexes of 1,2-bis (3,5-dimethylpyrazol-1-yl)-1,2-ethanediol were prepared by the reaction of transition metal salts (chloride, acetate, sulfate) with the ligand in ethanol solution. The composition of the complexes was confirmed by elemental analysis and molar conductivity measurements. The coordination modes of the ligand and counter-ions were established from IR spectra and DFT calculations.

A series of thiourea ligand , N-N'- diphenyl thiourea [I] [DPTH], N-phenyl-N'-[2-phenoyl] thiourea [II] [PPTH], N-phenyl-N'-[2-chlorophenyl] thiourea III [PCPTH], N-phenyl-N'- [5-chloro-2-methyl phenyl] thiourea IV [PCMPTH] and N- phenyl -N'-(5-chloro-2-methoxy phenyl) thiourea V (PCMTPTH) and their transition metal complexes of the type ML2 and ML2 Cl2 have been synthesized by reacting phenyl isothiocyanate with substituted aniline and transition metal salts. These newly synthesized ligands and their complexes were characterized by elemental and spectral studies. Based upon these studies it was revealed that in all the cases metal is coordinated through suphur group of thioamide of ligands. In case of nickel complexes, the nickel is coordinated to both oxygen and sulphur. In all the complexes metal is tetra coordinated forming a square planer geometry.

Distorted Octahedral

AbstractComplexes of arylidene salicyloyl- and benzoyl-hydrazones with the 3d metal ions, Cr(III), Mn(II), Fe(III), Co(II), Ni(II) and Cu(II), have been prepared using 2:1 ligand to metal ion ratio. Characterization of the isolated solids was accomplished by IR and electronic spectra, elemental analysis, and molar conductivity measurements. It is concluded that the two Schiff bases function as neutral bidentate ligands and the complexes formed assume a distorted octahedral geometry.

Abstract Bis-2-thienyldiethylaminophosphane (C4H3S)2PNEt2 (1) is introduced as a ligand for late transition metal complexes ([(H3C4S)2PNEt2]nMXmLp), with M = Ni(II), Au(I), Cu(I), Pd(II), Ir(I), X = Cl, Br and L = NCMe, COD, (2-7). Reactions of 1 with the late transition metal salts NiCl2·dme, (Me2S)AuCl, CuCl, PdCl2(PhCN)2, and [Ir(COD)Cl]2 yield the complexes [{(H3C4S)2PNEt2}2 · NiCl2] (2), [(H3C4S)2PNEt2 · AuCl] (3) [(H3C4S)2PNEt2·CuCl(CH3CN)]2 (4), [{(H3C4S)2PNEt2}2 · PdCl2] (5), [{(H3C4S)2PNEt2}2·PdCl2]2 (6), and [(H3C4S)2PNEt2·IrCl(COD)] (7). In addition, the transformation of 1 to the valuable chlorine-substituted starting material (H3C4S)2PCl (8) and the related conversion of 8 to the secondary phosphane (H3C4S)2PH (9) is reported. The complexes 2-7 are stable under inert gas conditions and were characterized by single-crystal X-ray studies, NMR spectroscopy, and elemental analysis.
