μ2-Acetato-κ2O:O′-(4,4′-bipyridyl-κN)tris(diethyl dithiophosphato-κ2S,S′)-μ3-sulfido-tri-μ2-sulfido-trimolybdenum(IV) diethyl ether monosolvate

In the title compound, [Mo3(CH3COO)(C4H10O2PS2)3S4(C10H8N2)]·C4H10O, the complex molecule has a trinuclear incomplete cuboidal structure which is coordinated by three kinds of ligands, namely, diethyl dithiophosphate, acetate and 4,4′-bipyridyl. If Mo—Mo bonds are ignored, each Mo atom can be considered as six-coordinated in a distorted octahedral 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 interactions link the trinuclear molecules related by translation in [100] into chains. The crystal packing exhibits short intermolecular 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.
