Cobalt(II), Nickel(II) and Copper(II) Complexes with 1-Pyridylimino-1-Phenyl-2-Hydroxyiminopropane

Abstract

A series of complexes having the formula [M(HL)₂(H₂O)₂]X₂

where M = Co (II), Ni(II) or Cu(II); X = Cl^–, Br^– and HL = 1-pyridylimino-

1-phenyl-2-hydroxyiminopropane has been synthesized by

allowing the ligand and the metal salts to react in the 2 : 1 molar

ratio in an ethanolic medium. Besides this, another series of complexes

of the type ML₂ has been synthesized by allowing the ligand

and metal acetates to react in the molar ratio 2 : 1 in an aqueous

medium made alkaline with NH₄OH. The complex CuL₂, when

allowed to react with CuX₂ salts, gives another series of binuclear

complexes having the formula Cu₂L₂X₂ [X = Cl^–, Br^–]. The

characterization of the complexes has been done on the basis of

elemental analyses, magnetic moment, conductance and spectral

studies.
