Di-μ-chlorotetrakis[1,3-dimethyl-2(3H)-imidazolethione]tetrachlorodibismuth(III) crystals are monoclinic, space group P21/n, with a 15.197(3), b 11.595(6), c 10.250(3) Å, and β 92.59(5)°; d.(exptl). = 2.13(2) and d.(calcd.) = 2.105 for Z = 2. Final R = 0.076. At. parameters are given. The structure can be described as 2 inversion center related octahedra sharing a common edge through Cl bridges. The dimethylimidazolethione mols. are trans to each other in the coordination sphere of each Bi atom, with Bi-S bond lengths of 2.844(4) and 2.845(4) Å.
