Synthesis and Structural Studies of Complexes of 4'-Methyl Acetophenone o-hydroxy 4-Benzamido Thiosemicarbazone with Oxovanadium(IV), Cobalt(II), Nickel(II) and Copper(II)

Abstract

Complexes of VO(IV), Co(II), Ni(II) and Cu(II) with 4'-methyl acetophenone o-hydroxy-4-benzamido thiosemicarbazone have been isolated and characterised on the basis of analytical data, molar conductance, magnetic susceptibility, electronic and infrared spectral measurements. Vanadyl complexes indicate square pyramidal geometry, while MLCI₂(H₂O)₂, ML(CH₃COO)₂ [M=Co(II), Ni(II)], octahedral; and [Cu(L)CI₂H₂O)₂, polymeric octahedral bridging and [Cu(CH₃COO)₂L)₂, square pyramidal geometry around the metal ion, where L = (C₁₇H₁₈N₄O₂S).
