Studies on Spectral Properties of Co(II), Ni(II) and Cu(II) Complexes with Ninhydrine and Ninhydrine Oximes

Abstract

A series of complexes of the type ML^1-3CI₂, ML^1-3CI₂Y₂, where
M = Co(II), Ni(II) and Cu(II), L¹= ninhydrine, L² = ninhydrine monoxime,
L³ = ninhydrine dioxime, Y = NH₃ or pyridine, have been synthesised and
characterised by elemental analysis, molar conductivity, electronic absorption
spectra and infrared spectra. On the basis of experimental data the
complexes of the type ML^1-3Cl₂ are found to be square planar whereas
complexes of the type ML^1-3Cl₂ Y₂ are found to be octahedral. The complexes
are found to be non-electrolytic in nature on the basis of molar
conductivity value.
