摘要：

Single crystals of a new tin titanate containing Sn2+, Sn2TiO4 Was prepared by high temperature reaction in an evacuated quartz tube and its crystal structure was determined by single crystal X-ray diffraction data. The tin titanate crystallizes in the tetragonal space group P4(2)/mbc with a = 8.490(2) and c = 5.923(3) angstrom, Z = 4 and the final R factors are R = 0.0497 and R-W = 0.0676 for 354 unique reflections. This tin titanate is isostructural with the low temperature form of Pb3O4(Pb22+Pb4+O4). This compound was oxidized above 600 degrees C accompanying the mass gain and finally changed to rutile-type solid solution (Sn,Ti)O-2. (C) 2009 Elsevier Ltd. All rights reserved.
