Abstract		It is shown by computer simulation of the transmission electron diffraction patterns and by structural considerations that the recently reported thin film for beta-Sn=2 is equivalent to the high pressure form SnO2-II. It crystallizes in a columbite-like structure either under the influence of the substrate in the case of epitaxial oxidation of alfa-SnO to SnO2 or under the influence of volume contraction conditioned by enhanced pressure and/or temperature during the cassiteritecolumbite transformation. The columbite-brookite-cassiterite structural relationship given and the possibility of the existence of a thin film fluorite-like polymorph is discussed.
