Abstract

A single molecular heterobimetallic complex, [Co ₂Ti(μ 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 CoTiO ₃-CoO composite thin films by aerosol-assisted chemical vapour deposition (AACVD). The precursor complex was prepared by interaction of Co(OAc) ₂.4H ₂O [OAc = (CH ₃COO ^-)] 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°C to give a residual mass corresponding to a CoTiO ₃-CoO composite material. Good-quality crystalline CoTiO ₃-CoO composite thin films deposited at 500°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 2-6 μm.
