SYNTHESIS AND CHARACTERIZATION OF SOME HETERO-METAL AND HOMO-METAL ARYLOXIDES OF COPPER(II)

Hetero- and homo-metallic aryloxides of copper(II) of the type, Cu[Ta(OAr')6]2 (1-4) [where OAr'= 3,5-dimethylphenoxo (1), 3,4-dimethylphenoxo (2), 2,4,6-trimethylphenoxo (3) and 4-chlorophenoxo (4)] and CuCl2-x(OAr')x(2,2'-bipy) (5-7) (OAr'= 3,4-dimethylphenoxo, x = 1 (8), x = 2 (5); 3,5-dimethylphenoxo, x = 2 (6); 2,4,6-trimethylphenoxo, x = 2 (7) have been synthesised and characterised by elemental analyses, spectroscopic (IR, electronic, UV-visible) studies, magnetic moments and molecular weights.
