SYNTHESIS OF 2-CHLORO-2-NORMAL-BUTYL-1,3-DITHIA-2-STANNACYCLOPENTANE AND THE CRYSTAL-STRUCTURE OF ITS 1,10-PHENANTHROLINE COMPLEX

2-Chloro-2-n-butyl-1,3-dithia-2-stannacyclopentane has been prepared and the structure of its 1,10-phenanthroline complex, C18H21ClN2S2Sn, has been determined by an X-ray diffraction study. The geometrical parameters indicate a distorted octahedral structure about the tin atom. The chlorine atom is trans to one nitrogen of the ligand in axial position, and the sulphur atoms, the carbon bonded to the tin and the other nitrogen form the equatorial plane. The SnS2C2 ring adopts an envelope form. No intermolecular contacts are observed.
