title: cis-Di-μ-oxido-bis-[(N,N-diethyl-dithio-carbamato-κS,S')oxidomolybdenum(V)](Mo-Mo) tetra-hydro-furan monosolvate.
abstract: The title compound, [Mo(2)(C(5)H(10)NS(2))(2)O(4)]·C(4)H(8)O, can be readily prepared in tetra-hydro-furan (THF) by an oxidation reaction between the Mo(IV) precursor [MoO(S(2)CNEt(2))(2)] with [ReMeO(3)]. The compound is an axially symmetric Mo(V) dimer (2 symmetry), in which the metal atoms exhibit a distorted square-pyramidal coordination environment. A THF mol-ecule was found to be equally disordered over two symmetry-related sites (around a twofold rotation axis), trans-coordinated to the apical oxido group and weakly inter-acting with the Mo(V) atoms [Mo-O = 2.6213 (19) Å]. In the crystal, some weak C-H⋯O inter-actions occur between the terminal oxido and neighbouring -CH(3) groups of an adjacent [Mo(μ-O)O(S(2)CNEt(2))](2) unit.
