Some chloro complexes of cobalt, nickel and copper with 4-pyridinealdoxime have been prepared in ethanolic solution. The complexes have stoichiometry ML2Cl2. The stereochemical configurations of the complexes have been deduced using spectral and magnetic properties. The cobalt and nickel complexes have octahedral structures while the copper complex has a tetragonal structure. The decomposition of the 4-pyridinealdoxime and its metal complexes have been studied by thermogravimetry and differential thermal analysis. Electrical conductivities at room temperature lie in the narrow range 3.68 x 10(-8) OMEGA-1 m-1 (for the copper complex) to 8.89 x 10(-8) OMEGA-1 m-1 (for the uncomplexed 4-pyridine-aldoxime). The current-voltage characteristics for all the compounds studied are ohmic in nature.
