Abstract
The X-ray crystallographic study of the title compounds has shown a remarkable structural variation induced by minor changes in the anion, [PhCH2SLi·NC5H5]∞ forming an infinite folded ladder polymer with Li–S rungs, removal of the CH2 group to give [PhSLi·(NC5H5)2]∞ resulting in a polymer containing an infinite Li–S chain, while the introduction of an Me group into the ortho-position in [o-MeC6H4SLi·(NC5H5)3] prevents association; all three structures have tetrahedral lithium whereas the co-ordination around sulphur varies from 2 to 4.Keywords
