The synthesis and characterization of zinc(II) and copper(II) complexes of embelin ( 1 ), C 17 H 26 O 4 , 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, ZnC 34 H 50 N 2 O 14 and CuC 34 H 54 O 10 for the zinc(II) and copper(II) complexes are proposed. KEY WORDS: Zinc(II) complex, Copper(II) complex, Embelin Bull. Chem. Soc. Ethiop. 2005, 19(2), 295-299.
