It has been shown with the aid of NMR that the reaction of aluminum acetylacetonate [Al(acac)3] with AlCl3 and CHCl3 results in the formation of Al(acac)2Cl and Al(acac)Cl2. The dimensions of the complexes formed have been determined, and it has been concluded on their basis that the complexes are monomeric. The structures of the compounds formed have been proposed. The data obtained attest to the fact that Al(acac)Cl2 has a tetrahedral configuration of ligands.

solution. For a higher concentration and a lower temperature the trimeric complex is predominant. An X-ray structure determination revealed that in the solid state dichloroaluminium acetylacetonate occurs exclusively as the trimeric complex and itsmolecularstructure comprises the [Al2Cl2(acac)3]+ cation and the [AlCl4]− anion. The cation consists of two five-coordinated Al atoms interconnected by a double
