Synthesis, Magnetic and Spectral Studies on Copper(II) Complexes with Bidentate Thiosemicarbazones

Abstract

The synthesis and spectral characterization of new copper(II) complexes of the composition CuL₂X₂ [where L = 2‐methylcyclohexanone thiosemicarbazone (L¹) and ⁴ N‐methyl thiosemi‐carbazone (L²) and X = Cl, NO₃, and 0.5SO₄] are reported. All the complexes have been characterized by IR, electronic, EPR, and mass spectral studies, magnetic moments, and conductivity measurements. A tetragonal geometry has been assigned to all the complexes except the sulfato complexes which were found to have five coordinated square‐pyramidal geometry.

Keywords:
