Palladium(II)- and Platinum(II)-complexes of Schiff Bases Derived from Salicylaldehyde and Alkylamines

Abstract

revealed that it depends much upon the nature of the metal ion as well as upon that of the ligand whether the quadri-co-ordinate complex of a transition element takes a squareplanar configuration or a configuration distorted from it. Thus, the stability of the tetrahedral co-ordination around the metal ion, as compared with that of the square-planar one, is higher for cobalt(II)1), a little lower for nickel(II)2), and much lower for copper(II)3).
