Studies of SomeTransition Metal Complexes with β-Hydroxy α-Naphthalidine Anthranilino Hydroxamic Acid

Abstract

A series of complexes of the type MLX₃ [M = Co(II), Cu(II) and Ni(II),
X = H₂O, pyridine, and α , β or γ picolines] have been synthesized with the
ligand  β-hydroxy  α-naphthalidine anthranilino hydroxamic acid, H₂L.
Characterization of the ligand as well as complexes have been done on the
basis of elemental analysis, spectral studies and conductivity and magnetic
susceptibility measurements. Ligand has been found to coordinate through
two of its nitrogen and one oxygen atoms. The complexes are found to be
octahedral, the remaining three coordination sites are satisfied by oxygen
of H₂O or nitrogen of nitrogen donors such as pyridine and α ,  β or γ
picolines.
