Crystallization of 1:1 stoicheiometric dimethylformamide solutions of [Bi(S2CNEt2)I2] and [NEt4]I yields a complex of stoicheiometry [NEt4] [Bi(S2CNEt2)I3]. Single-crystal X-ray diffraction studies show it to be [NEt4]2[I2(Et2NCS 2)BiI2Bi(S2CNEt2)I2], with a centrosymmetric anion containing iodine bridges. Use of [NEt4]Br instead, yields the isostructural monobromide; its structure has also been determined and the bromine found to occupy one of the non-bridging co-ordination positions about the bismuth atom. The unit cell is triclinic, with a ca. 13.0, b ca. 10.7, c ca. 9.6 Å, α ca. 68, β ca. 79, and γ ca. 75°.
