Two heterobimetallic precursors [Zn(TFA)(3)(mu-OH)Cu(3)(dmae)(3)Cl]center dot THF (1) and [Zn(TFA)(4)Cu(3)(dmae)(4)] (2) [dmae = N, N-dimethylaminoethanolate and TFA = trifluoroacetate], have been synthesized and characterized by their melting points, elemental analysis, FT-IR spectroscopy, mass spectrometry, TGA and single crystal X-ray diffraction methods. Both complexes were used to deposit thin films of Cu-ZnO composite on glass substrates by aerosol assisted chemical vapor deposition (Lambda Lambda CVD) method. The films were characterized by "scotch tape" test for adhesion, thickness measurement as a function of temperature, EDX for composition, SEM for surface morphology and XRD for crystalline phases. Thin film deposition studies at 250, 325, 400, 475 degrees C indicated the increase in thickness with temperature reaching a maximum at 400 degrees C and then decreasing. EDX and PXRD results showed the uniform distribution of cubic metallic copper and hexagonal zinc oxide phases which make them useful for nanocatalysis on structured surfaces.
