Syntheses and structures of diorgano(halo- orpseudohalo-)(1,3-dithiole-2-thione-4,5-dithiolato)-stannates (1-), [Q][R2SnX(dmit)] (Q=onium cation; X=halide orpseudohalide)

Ionic compounds, [Q] [R2SnX(dmit)][dmit=1,3-dithiole-2-thione-dithiolate; Q=1,4-dimethylpyridinium or tetraalkylammonium; R=Phor alkyl; X=Cl, Br, I, NCS, NCSe, or N3] have been obtained by (a) from R2SnX2 and [Q]2[Zn(dmit)2] in the presence of excess QX,(b) from halide exchange reactions in acetone solution between [Q] [R2SnCl(dmit)]and a halide or pseudohalide source, or (c) by addition of QX to [R2Sn(dmit)]. Crystalstructure determinations of [NEt4] [Ph2SnI(dmit)] and [1,4-Me2pyridiniuml [Ph2SnBr(dmit)] as well as of the mixed halides, [Ph2SnClnI1-n(dmit)] (n=0.57, 0.42 or0.22), indicated that the tin atoms have distorted trigonal bipyramidal geometries in the anions,with the X ligand and a dithiolato atom in the axial sites. The [R2SnX(dmit)]- anions remain essentially intact in organic solvents, but lose X- on extractionwith H2O to give the neutral species, R2Sn(dmit).
