Ketonic complexes of acetylacetone and ethyl acetoacetate with divalent transition metals

Several new coordination compounds are reported with 2,4-pentanedione (acacH) and ethyl 3-oxobutanoate (etaaH) as the neutral bidentate oxygen donor ligands, viz. [M(acacH)3]- (InCl4)2 and [M(etaaH)3](InCl4)2 where M is Mg(II), Mn(II), Fe(II), Co(II), Ni(II) and Zn(II). In the complexes the ligands are present in their ketonic form. The metal ions are surrounded octahedrally by six oxygen atoms.
