Abstract

The synthesis and characterization of zinc(II) and copper(II) complexes of embelin (1), C17H26O4, are described. Zinc(II) and copper(II) ions reacted with (1) (an orange compound) in a 1:2 ratio to yield purple and green complexes, respectively. IR analysis of the two complexes showed that the metal ions were co-ordinated through the carbonyl and the hydroxyl oxygen atoms. Elemental analyses (AAS and C, H, N) of the complexes gave values that are consistent with six co-ordinate octahedral geometry about the metal ions. Molecular formulae, ZnC34H50N2O14 and CuC34H54O10 for the zinc(II) and copper(II) complexes are proposed.
