The ionic complexes [Q][Ph2Sb(dmit)2] (4; Q = NEt4 or 1,4-Me2-pyridinium) and [Net4][(p-tolyl)2Sb(dmit)2] (5) have been prepared from [Q]2[Zn(dmit)2] and Ar2SbCl3 in the presence of KSCN (H2-dmit = 4,5-dimercapto-1,3-dithiole-2-thione). As shown by X-ray crystallography for 4 (Q = NEt4) and 5, these complexes contain distorted octahedral anions with cis-aryl groups : the C - Sb - C angles in 4 (Q = NEt4) and 5 are 93.1(2) and 95.3(5)°, respectively. The dmit chelates are unsymmetrically bonded to antimony in both 4 (Q = NEt4) and 5 with the longer bonds trans to the aryl groups (for both compounds, the Sb - S bond lengths are in the ranges, 2.614 to 2.636 and 2.530-2.550 A).
