Abstract
Two quadridentate chelating agents, 4,4′-dimethyl-2,2′-bis(salicylideneaminomethyl)diphenyl ether and 4,4′-dimethyl-2,2′-bis(salicylideneaminoinethyl)diphenylarnine, which may form a metal complex with a ten-membered chelate ring, were synthesized by a sequence of steps. The cobalt(II), nickel(II), copper(II), and zinc(II) complexes could be derived from the ligands. Their configurations around the central divalent metal ion were explored on the basis of the absorption in the ligand field in a solution. A tetrahedral configuration for cobalt(II) complexes as well as the zinc(II) complexes, and a pseudo-tetrahedral configuration for the nickel(II) and copper(II) complexes, were concluded.This publication has 11 references indexed in Scilit:
