Abstract

Recrystallization of the complexes [Bi(S2CNEt2)X2], X = Cl, Br, or I, from dimethylformamide-n-butanol results in the formation of [Bi5(S2CNEt2)8X 7]·.dmf (dmf = dimethylformamide). The three complexes are isomorphous and have been characterized structurally by single-crystal X-ray diffraction, showing the structure to be comprised of a [BiX6]3- species acting as a central bridging unit by co-ordinating to four surrounding [Bi(S2CNEt2)2]+ species, with an additional halide bridge preserving electroneutrality. The overall unit has crystallographically imposed 2 symmetry; the unit cell is monoclinic, space group C2/c, with a ca. 19.5, b ca. 20.5, c ca 21.5 Å, and β ca. 102.5°. Recrystallization of [Bi(S2NCEt2)Br2] from pyridine-n-butanol results in the formation of [NC5H6]2[Bi4(S2CNEt 2)4Br10] (solvated). The complex anion has a crystallographically imposed two-fold symmetry element.
