catena-Poly[[diaquazinc(II)]--L-cysteinato(2-)-⁴S:S,N,O-[di--sulfido-bis[oxidomolybdate(V)](Mo-Mo)]--L-cysteinato(2-)-⁴S,N,O:S]

Abstract: The title compound, [Mo₂Zn(C₃H₅NO₂S)₂O₂S₂(H₂O)₂], forms a one-dimensional chain. The cysteine S atom of the dinuclear molybdenum complex anion coordinates to the zinc ion, which has a tetrahedral environment by the additional coordination of two water molecules. The one-dimensional chains are connected to each other by hydrogen bonds. The Zn-S(cysteine) distances [2.3599 (6) and 2.3072 (6) Å] are close to the value in ZnS (2.35 Å). The distances and angles within the complex are very close to those reported for the sodium and potassium di--sulfide species.
