Die Kristallstruktur von Tris(trimethylstannyl) acetonitril / Crystal Structure of Tris(trimethylstannyl)- acetonitrile

Abstract

Single crystals of (Me3Sn)3CCN were obtained by the reaction of tris(trimethylstannyl)amine with boiling acetonitrile in the presence of potassium fluoride and trimethylarsane. The compound has been characterized by IR spectroscopy and by a crystal structure determination. Space group P21/n, Z = 4; lattice dimensions at -50 °C: a = 975.4(1), b = 1316.3(2), c = 1485.3(1), β = 98.55(1)°, R = 0.029. (Me3Sn)3CCN forms monomeric molecules with a linear CCN axis (bond angle 178.7(6)°) and bond lengths of CC = 142.1(8) pm and CN = 114.5(8) pm
