Studies of Spectral and Magnetic Behaviour of Some Complexes of Co(II), Ni(II) and Cu(II) Ions with 2-(Acetylacetonato) Imino Aceto Hydroxamine Acid

Abstract

A series of complexes of the type MLB₃ [M = Co(II), Ni(II) and
Cu(II) ions, B = H₂O, pyridine and  γ-picoline] have been synthesised
with hydroxamic acid as ligand, H₂L. Characterisation of the
ligand and the complexes has been done on the basis of elemental
analysis, spectral stqdies, magnetic susceptibility and electrical conductivity
measurements. The ligand has been found to coordinate
through two nitrogen and one oxygen atoms. Since the complexes
are found to be octahedral, the remaining three coordination sites
are satisfied by oxygen of H₂O and nitrogen donor molecules such
as pyridine and  γ-picoline.
