μ2-Acetato-κ2 O:O′-(4,4′-bipyridyl-κN)tris­(diethyl di­thio­phosphato-κ2 S,S′)-μ3-sulfido-tri-μ2-sulfido-trimolybdenum(IV) diethyl ether monosolvate

In the title compound, [Mo3(CH3COO)(C4H10O2PS2)3S4(C10H8N2)]·C4H10O, the complex mol-ecule has a trinuclear incomplete cuboidal structure which is coordinated by three kinds of ligands, namely, diethyl di-thio-phosphate, acetate and 4,4'-bipyridyl. If Mo-Mo bonds are ignored, each Mo atom can be considered as six-coordinated in a distorted octa-hedral geometry. The Mo-Mo distance of 2.6880 (5) Å for two the Mo atoms bridged by the acetate ligand is shorter than the other two Mo-Mo distances [2.7490 (5) and 2.7566 (5) Å]. One ethyl group is disordered between two conformations in a 0.65 (3):0.35 (3) ratio. In the crystal, weak C-H⋯O inter-actions link the trinuclear mol-ecules related by translation in [100] into chains. The crystal packing exhibits short inter-molecular S⋯S contacts of 3.1886 (13) Å. In other words, in this crystal packing, a supramolecular structure is constructed by the C-H⋯O and S⋯S interactions.
