Characterization of Some Copper(II), Nickel(II) and Cobalt(II) Coordination Compounds with Schiff Bases Derived from 1,2-Dipenyl-1-Hydroxyiminoethan-2-One and Aromatic Amines

Abstract

A number of coordination compounds of the types [M(L^1–7)₂], [M(HL^1–7)₂Cl₂] [M =Co(II), Ni(II) or Cu(II)] and [CuL^1–7 Cl], where HL^1–7 = Schiff bases derived by condensing 1,2-diphenyl-1-hydroxyiminoethan-2-one with aniline (HL¹), 2-methylaniline (HL²), 3-methylaniline (HL³), 4-methylaniline (HL⁴), 2-nitroaniline (HL⁵), 3-nitroaniline (HL⁶) or 4-nitroaniline (HL⁷) have been synthesised and characterised on the basis of elemental analyses, magnetic susceptibility, infrared and electronic spectral data.
