Abstract

Bis(1,3-dithiole-2-one-4,5-dithiolato)antimonate(1-) salts, [Q][Sb(C3OS4)(2)], [Q][Sb(dmio)(2)] (3: Q = NEt4, 1,4-dimethylpyridinium (DMP), PPh4 or ferrocenyl-CH2NMe3) and bis(1,3-dithiole-2-thione-4,5-dithiolato)antimonate(1-) salts, [Q][Sb(C3S5)(2)], [Q][Sb(dmit)(2)] (1: Q = AsPh4 or NBu4) have been obtained from SbBr3-NaSCN and [Q](2)[Zn(dmio)(2)]or [Q](2)[Zn(dmio)(2)]. The crystal structures of (1: Q = AsPh4 or NBu4) and (3: Q = NEt4 and DMP) have been determined. In all cases, the Sb centres are 6-coordinated and, with the inclusion of the lone pair, are considered to have pseudo pentagonal bipyramidal structures. The interanion interactions in these and related complexes are compared. (C) 2002 Elsevier Science Ltd. All rights reserved.
