The following metal complexes containing ethyl acetoacetate (etacH) or ethyl malonate (etmalH) as a neutral ligand have been prepared: CoCl<SUB>2</SUB>L, CoBr<SUB>2</SUB>L, ZnCl<SUB>2</SUB>L (L=etacH or etmalH), and MnBr<SUB>2</SUB>(etmalH). These compounds are all hygroscopic and unstable, releasing the ester ligand below 100°C <I>in vacuo</I> or in donor solvents. The infrared spectra show that the ratio of keto and enol tautomers in etacH complexes is similar to that for the free ligand. The ν(C=O) band attributable to the enol tautomer of etmalH is observed in the complexes, though not in the free ligand. The electronic spectra measured in Nujol suggest that the cobalt(II) complexes are tetrahedral. The structure of MnBr<SUB>2</SUB>(etmalH) is not yet certain.
