The products obtained by the reactions of Ni(OAc)(2)center dot 4H(2)O with Hpot (Hpot = 5-phenyl-1,3,4-oxadiazole-2-thione) and [K(H(2)fchc)] (potassium N'-(furan-2-carbonyl) hydrazine carbodithioate), on treatment with excess of ethylenediamine (en), gave mixed ligand complexes [Ni(pot)(2)(en)(2)] (1) and [Ni(fot)(2)(en)(2)] (2) (fot = 5-furan-(1,3,4)-oxadiazole-2-thione). These complexes have been characterized with the aid of elemental analyses, IR, magnetic susceptibility and single crystal X-ray studies. In both complexes, the heterocyclic ligand coordinates through oxadiazole nitrogen, and the ligand exists as the thione form. The complexes 1 and 2 have distorted octahedral geometries around the centrosymmetric Ni(II) center with trans oxadiazole ligands. Both complexes show extended hydrogen bonding to give a supramolecular framework.
