The synthesis, characterization and spectral studies of Co(II), Ni(II), Cu(II), Zn(II) and Cd(II) complexes with N,N-bis(2-{[(2-methyl-2-phenyl-1,3-dioxolan-4-yl) methyl]amino}butyl) N′,N′-dihydroxyethanediimidamide

Abstract

CoII, NiII, CuII, ZnII and CdII complexes of N,N-bis(2-{[(2-methyl-2-phenyl-1,3-dioxolan-4-yl)methyl]amino}butyl)N′,N′-dihydroxyethanediimidamide (LH2) were synthesized and characterized by elemental analyses, IR, 1H- and 13C-NMR spectra, electronic spectra, magnetic susceptibility measurements, conductivity measurements and thermogravimetric analyses (TGA). The CoII, NiII and CuII complexes of LH2 were synthesized with 1 : 2 metal ligand stoichiometry. ZnII and CdII complexes with LH2 have a metal ligand ratio of 1 : 1. The reaction of LH2 with CoII, NiII, CuII, ZnII and CdII chloride give complexes Ni(LH)2, Cu(LH)2, Zn(LH2)(Cl)2, Cd(LH2)(Cl)2, respectively.
