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.
