Preparation, thermal, structural and electrical studies of dichlorohexa (anthranilamide) cobalt(II) and dichloro (anthranilamide) copper(II)

Abstract

The chloro compounds of anthranilamide with cobalt and copper were prepared in aqueous solution. Solid compounds were isolated and characterised by analysis, magnetic moments, and vibrational and electronic spectra. They have octahedral structures. Thermogravimetry and differential thermal analysis show that the compounds lose organic ligand and halogen to give the metal oxide. Electrical conductivities at room temperature show ohmic behaviour and lie in the range from 4.50 × 10 −8Ω −1m −1 (for the cobalt complex) to 8.80 × 10 −8Ω −1 m −1 (for the copper complex). The temperature dependence of conductivity was determined for the compounds and was used to provide a measure of the activation energies for conduction.
