Synthesis and Characterization of Some Homometallic and Hetrometallic Precursors of Copper, Zinc and Palladium Metal Ions

We have extensively explored the use of aminoalkoxides, -diketonates and carboxylates of two different metals for the preparation of heterobimetallic complexes in which chelating and/or bridging ligands can coordinate to the second metal, thus leading towards each metal center to be coordinatively saturated without the need for the formation of extensive -alkoxide networks. The resulting complexes are forced into a strictly molecular regime and the metal oxide core is wrapped in a blanket of organic ligands thus making the complex soluble in most common solvents. In view of the interesting structural features and suitability of heterometallic alkoxides (supported by chelating ligands) as precursors for oxide-ceramic materials, studies have been recently extended to novel types of heterometallic metal complexes [Zn(acac)2(dmaeH)], Pd(dmae)(dmaeHCl) derived from acetylaacetone and 2,4 pentanedione.
