New metal complexes of oxadiazole-
2-thione-based ligands are reported. The reaction
of 2-methyl-benzoic acid hydrazide, thiophen-2-ylacetic
acid hydrazide and isonicotinic acid hydrazide
with carbon disulfide and potassium hydroxide in
methanol resulted in the formation of the newligands
namely; 5-o-tolyl-3H-[1,3,4]oxadiazole-2-thione
(L1), 5-thiophen-2-ylmethyl-3H-[1,3,4]oxadiazole-
2-thione (L2) and 5-isoquinolin-3-yl-3H-
[1,3,4]oxadiazole-2-thione (L3), respectively. Monomeric
metal complexes of the general formula
[M(Ln)(en)2]. (where MCl2. XH2O= Co(II), Ni(II)
and Zn(II); X= 6, 6, 0 en= ethylenediamine; n=1, 2,
3)were achieved fromthe reaction heterothe
appropriate ligand in presence of ethylenediamine
as a coligand. Compounds were characterised by
spectroscopic methods (NMR, mass spectra, FTIR
andUV-Vis spectroscopy), elemental analyses,magnetic
susceptibility, atomic absorption, chloride content,
andmelting point. Based on above analysis the
suggested geometry about metal atoms is distorted
