Descrição: Direct treatment (1:1) of MCl^sub 3^ (M = Sc, Y or La) with SnCl4 in thf provides colourless compounds of the type ScSnCl^sub 7^(thf)^sub 5^ and MSnCl^sub 7^(thf)^sub 6^ (M = Y, La), which have been characterised by elemental analysis and spectroscopic studies. An X-ray determination of ScSnCl^sub 7^(thf)^sub 5^ reveals an ionic structure comprising individual six-coordinate [ScCl^sub 2^(thf)^sub 4^]^sup +^ cations and [SnCl^sub 5^(thf)]^sup -^anions. The cations feature an octahedral metal geometry in which a linear Cl-Sc-Cl unit is surrounded by an equatorial girdle of four solvent (thf) molecules.[PUBLICATION ABSTRACT]
