The title compound, [{Mo3S4(Tpms)2}2(μ-O)(μ-Cl)2]·5CH2Cl2 (Tpms = tris(pyrazolyl)methanesulfonate), crystallized in the monoclinic space group C2/c with the following unit-cell parameters: a = 24.509(7)Å, b = 29.273(6)Å, c = 16.490(5)Å, β = 132.942(3)°, V = 8661(4)Å3 and Z = 4. The crystal structure was solved by direct methods, and refined by full-matrix least-squares procedures to a final R-value of 0.0798 for 7989 observed reflections. A Tpms ligand coordinated to the molybdenum atom through the two nitrogen atoms in two pyrazole rings and one oxygen atom in a sulfonato group. Another Tpms ligand coordinated to the molybdenum atom through three nitrogen atoms in three pyrazolyl rings. The remaining molybdenum atom was bridged to an adjacent molybdenum atom in another Mo3S4 core by two chloride anions and one oxygen atom.
