摘要：

The preparation of NH4TiOF3, NaTiOF3·H2O, KTiOF3·0.5H2O, TlTiOF3·0.5H2O, [Co(NH3)6][TiOF3]3. H2O, [Co(NH3)6]2[TiOF4]3, BaTiOF4·0.5H2O, K6Ti4O3F16 Rb5HTi4O3F16, Ba3Ti4O3(OH)F15·2H2O are described. The compounds are characterised by chemical analyses and recording of X-ray diffraction data. On dehydration over P2O5 in vacuum at room temperature anhydrous [Co(NH3)6][TiOF3]3 and Ba3Ti4O3(OH)F15 are formed. The IR spectra of the compounds show broad bands in the region 700-900 cm-1 which suggests the presence of -Ti-O-Ti-O- chains in the compounds. The compounds show the usual bands of Ti-F, N-H, O-H and H-O-H. TG analyses show the compounds lose weight continuously with the rise of temperature. On isothermal heating of TlTiOF3O·5H2O and BaTiOF4·0.5H2O at 200°C the corresponding anhydrous compounds are formed. © 1979.
