The preparation, characterisation and thermal analysis studies on complexes of cobalt(II), nickel(II), copper(II) and zinc(II) with phenanthridine

Abstract

A series of chloro and bromo complexes of cobalt, nickel, copper and zinc with phenanthridine have been prepared. The chloro and bromo complexes of cobalt and zinc, and the bromo complex of nickel have tetrahedral structures. The chloro and bromo complexes of copper have tetragonal structures while the chloro complex of nickel has a polymeric octahedral structure. The stereochemical configurations were deduced using spectral and magnetic studies. The decomposition of each complex has been investigated using thermogravimetry and differential thermal analysis.
