Adsorption-sensitive thin film elements on the basis of nanoscale oxide materials,
especially nanoscale tin dioxide, are widely used in the modern gas analyzers. Wellknown production methods of nanoscale metal oxide like tin dioxide are liquid
phase chemical methods: sol-gel method, chemical solution deposition, chemical
vapor deposition, etc. [1–3]. One of the main stages in such technologies is the
decomposition of one, thermally unstable, compound to produce tin dioxide as the final product. The production of such compounds is limited enough. The limited and contradictory literature data on their physical and chemical properties determined the necessity to find a suitable precursor for nanosized tin
dioxide production. Previously, authors [4] by means of the method of chemical
precipitation from solution proposed the preparation technique for SnO2 film
production with polyvinyl acetate (PVA) as a structuring additive. The complex
bis(acetylacetonato)dichlorotin (BADCT) was used as a precursor of tin dioxide.
In [5], it was firstly mentioned the fact of obtaining of BADCT (Sn(C5H7O2)2Cl2)
in 1903. Earlier in the literature [5–8], it was reported the BADCT production using
chloroform [5] or dry toluene [8] as solvents. A special feature of our method is using of water as a solvent.
