Preparation and Structures of Chlorostannates(II). I. Some New Trichlorostannates of Monovalent CationsKSnCl3 · 1/2 CH3CN is obtained by recrystallizing KSnC13 from acetonitrile. The compound forms monoclinic crystals, space group P21/c (a = 4.525(6), b = 20.34(2), c = 8.061(7) Å, β = 90.93(9)°). [Cu(CH3CN)3]SnCl3 is prepared by reacting equimolar amounts of CuCl and SnCl2 in acetonitrile. It crystallizes in the monoclinic space group P21/n (a = 7.984(9), b = 20.77(2), c = 8.34(2) Å, β = 101.6(1)°). Whereas in KSnCl3 · l/2 CH3CN there is a three dimensional connection of the SnCl3- ions, in which the potassium ions participate, the trichlorostannate ions in [Cu(CH3CN)3]SnCl3 are linked to one dimensional chains by Sn…Cl bridges.
Notes:
KSnCl3 · 1/2 CH3CN wird durch Umkristallisieren von KSnCl3 aus Acetonitril erhalten. Die Verbindung kristallisiert monoklin, Raumgruppe P21/c (a = 4,525(6), b = 20,34(2), c = 8,061(7) Å, β = 90,93(9)°). Durch Umsetzung von CuCl mit einer äquimolaren Menge an SnCl2 in Acetonitril erhält man [Cu(CH3CN)3]SnCl3 das in der monoklinen Raumgruppe P21/n kristallisiert (a = 7,984(9), b = 20,77(2), c = 8,34(2) Å β = 101,6(1)°). Während in KSnCl3 · 1/2 CH3CN eine dreidimensionale Verknüpfung der SnCl3minus;-lonen vorliegt, an der auch die Kaliumionen beteiligt sind, sind die Trichlorostannationen in [Cu(CH3CN)3]SnCl3 durch Sn…Cl-Brücken zu eindimensionalen Ketten verknüpft.
