| Abstract | A single molecular heterobimetallic complex, [Co2Ti(mu 3-O)(TFA)6(THF)3] (1) [TFA?=?trifluoroacetate, THF?=?tetrahydrofuran], was synthesized, structurally and spectroscopically characterized and implemented as a single-source precursor for the preparation of CoTiO3CoO composite thin films by aerosol-assisted chemical vapour deposition (AACVD). The precursor complex was prepared by interaction of Co(OAc)2.4H2O [OAc?=?(CH3COO-)] with Ti(iso-propoxide)4 in the presence of trifluoroacetic acid in THF, and was analysed by melting point, CHN, FT-IR, single-crystal X-ray diffraction and thermogravimetric analysis. The precursor complex thermally decomposed at 480 degrees C to give a residual mass corresponding to a CoTiO3CoO composite material. Good-quality crystalline CoTiO3CoO composite thin films deposited at 500 degrees C by AACVD and characterized through powder X-ray diffraction and scanning electron microscopy/energy-dispersive X-ray spectroscopy show that the crystallites have a rose-flower-like morphology with an average petal size in the range of 26 mu m.
