Preparation and X-ray characterisation of the first heteroleptic hydrocarbon-soluble tin(II) pseudohalide, Sn(NCS)[N(SiMe3)2]
摘要:
Treatment of equivalent portions of Sn(NCS)2 and Sn(NR2)2 (R = SiMe3) in Et2O yielded the toluene-soluble, crystalline, colourless Sn(NCS) (NR2), which X-ray crystallography shows to be a V-shaped monomer [N-Sn-N 94.1 (2), Sn-N-CS 171.0(5)-degrees] with weak intermolecular bonding to neighbouring units [Sn...S' 3.047(2) and Sn...S" 3.316(2) angstrom; S'...Sn...S" 178.4(1)-degrees].
