SYNTHESES AND CHARACTERIZATION OF 4-(11-CHLORO-3,6,9-TRIOXAUNDECYLOXY) PHENYLAMINO-GLYOXIME AND ITS COMPLEXES WITH COPPER(II), NICKEL(II), AND COBALT(II)

ABSTRACT

A novel vic-dioxime ligand containing ethyleneoxy groups, 4-(11-chloro-3,6,9-trioxaundecyloxy)phenylaminoglyoxime (LH₂) has been prepared from 1-amino-4-(11-chloro-3,6,9-trioxaundecyloxy)benzene and monochloro anti-glyoxime. Its complexes, Ni(LH)₂, Cu(LH)₂ and Co(LH)₂, have been synthesized. The analytical data show that the metal to ligand ratio in the complexes is 1:2. The complexes are formed by coordination of N,N atoms of the ligand. The structures of the oxime ligand (LH₂) and its complexes were elucidated by ¹H NMR, IR, UV.-Visible and elemental analyses techniques.
