N2 - Direct treatment (1:1) of MCl3 (M = Sc, Y or La) with SnCl4 in thf pro vides colourless compounds of the type ScSnCl7(thf)5 and MSnCl7(thf)6 (M = Y, La), which have been characterised by elemental analysis and spectroscopic studies. An X-ray determination of ScSnCl7(thf)5 reveals an ionic structure comprising individual six-coordinate [ScCl2(thf)4]+ cations and [SnCl5(thf)]- 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.
