A well-defined heterobimetallic complex, [Cu4Zr2(mu(4)-O)(2)(dmae)(4)(OAc)(8)]center dot 2H(2)O 1 where dmae = N,N-dimethylaminoethanolato and OAc = acetato, has been constructed by the chemical reaction of Cu(OAc)(2)center dot 2H(2)O with Zr(dmae)(4) in THF. Complex 1 was characterized by its melting point, elemental analysis, infrared spectroscopy, thermogravimetric analysis and single crystal X-ray diffraction. X-ray crystallography shows that complex 1 crystallizes in the monoclinic space group P21/n with the cell dimensions a = 14.7414(5), b = 11.7378(4) and c = 14.8196(5) angstrom and beta = 94.826(2)degrees. The nature of the thermolysis of 1 showed its aptitude to give a 1:1 CuZrO3:CuO composite oxide material at 575 degrees C. The high solubility and stability of 1 in common organic solvents suggest its efficacy as a single source precursor (SSP) in the aerosol assisted chemical vapor deposition technique for the formation of a CuZrO3-CuO composite thin film on a soda lime glass substrate under an air atmosphere. Thin film properties, such as crystallinity, identification of deposited phases, surface morphology and chemical compositions were probed by X-ray diffraction, scanning electron microscopy and energy dispersive X-ray analysis, which ascertained the evolution of good quality crystalline hemispherical architecture composite oxide thin films from 1.
