Synthesis and Characterization of New Ligand N,N-Dimethyl-4-[(E)-(2-{5-[2-(5-phenyl-1,3,4-oxadiazol-2-yl)hydrazinyl]-1,3,4-thiadiazol-2-cyl}hydrazinylidene)methyl]aniline and Transition Metal Complexes

A new ligand N,N-dimethyl-4-((2-(5-(2-(5-phenyl-1,3,4-oxadiazole-2-yl)hydrazinyl)-1,3,4-thiadiazol-2-yphydrazono)methyl)aniline and its Cr(III),Ni(II) and Co(II) complexes were synthesized, and characterized by FTIR, H-1-NMR, and mass spectral data. The ligand acts as bidentate ligand coordinating through the nitrogen atom. The program of hyperchem 8 has been used for theoretical accounts using PM3 method to study the electrostatic potential that provided good information to determine the appropriate positioning complexity. Based on the spectral data, the octahedral geometry for the Cr(III), tetrahedral geometry for Co(II), and square planar geometry for Ni (II) have been suggested.
