Br. Carson et al., THERMAL AND STRUCTURAL STUDIES OF THE CHLORO COMPLEXES OF COBALT, NICKEL AND COPPER WITH 3-PHENYLPYRIDINE, Journal of thermal analysis, 45(3), 1995, pp. 369-374
The chloro complexes of cobalt, nickel and copper with 3-phenylpyridin
e were prepared in ethanolic solution from which solid compounds were
isolated. The cobalt and copper complexes have stoichiometry M(2)LCl(4
) while the nickel complex has stoichiometry NiLCl(2). The suggested s
tructure for the cobalt and copper complexes is tetrahedral, while for
the nickel complex it is octahedral. Thermal analysis studies show th
at the cobalt and copper complexes form intermediate complexes before
their metal oxides are produced. The nickel complex also forms an inte
rmediate complex and then nickel chloride before the nickel oxide is o
btained.
