Thermal, spectral and magnetic studies of the chloro complexes of cobalt(II), nickel(II) and copper(II) with phenetidine

Abstract

The chloro compounds of p-phenetidine with cobalt(II), nickel(II) and copper(II) were prepared in ethanolic solution from which solid compounds were isolated. The suggested structure for the cobalt compound is tetrahedral, while for the nickel and copper it is octahedral. The techniques of thermogravimetry and differential thermal analysis show that the compounds dichloro-bis( p-phenetidine) cobalt(II) and dichloro-bis( p-phenetidine) nickel(II) form intermediate compounds before the metal oxide is produced. The compound dichloro-bis( p-phenetidine) copper(II) decomposes with loss of the phenetidine and chlorine and the formation of copper oxide.
