摘要：

The title compound [C2H5N4S]4[Bi2Br10]; [HL]4[Bi2Br10] (L = 2,5-diamino- 1,3,4-thiadiazole) was prepared and characterized by means of X-ray, and IR measurements. The structure was solved by the heavy-atom method, and least-squares refinement of structural parameters led to a conventional R factor of 0.036 (R(w) = 0.032) for 2425 independent reflections. The crystal consists of a condensed [Bi2Br10]4- anion and four HL+ cations. The anion has three bromine atoms involved in hydrogen bonds with N-bonded H atoms; the nonprotonated nitrogen atom of the cation is involved in hydrogen bonds too. The metal atoms have distorted octahedral geometry.
