Abstract

The nanometric mixed tin-titanium oxide doped with a M⁵⁺ cation was recently shown as a promising thermoelectric material. We report here synthesis of novel molecular precursors for above material using a convenient approach of reacting a metal chloride with a metal alkoxide. Heterometallic complexes with simple addition formula [(EtOH)₂(OEt) ₂Ti(μ-OEt)₂SnCl₄] (1·EtOH) and [(EtOH)(OEt)₃Ta(μ-OEt)₂SnCl₄] (2) were isolated in quantitative yield, which on recrystallization from isopropanol afforded mixed-alkoxide complexes [(PrⁱOH)₂(OPr ⁱ)₂Ti(μ-OEt)₂SnCl₄] (3) and [(PrⁱOH)(OPrⁱ)₃Ta(μ-OEt) ₂SnCl₄] (4), respectively, thus indicating the robustness of the heterometallic M(μ-OEt)₂Sn core in the solution phase. Facile conversion of these precursors to halide-free spinodal form of Ta ⁵⁺-doped TiO₂-SnO₂ as a potential thermoelectric material is reported.
