Catena-Poly[[diaquazinc(II)]-μ-L-cysteinato(2−)-κ4S:S,N,O-[di-μ-sulfido-bis[oxidomolybdate(V)](Mo—Mo)]-μ-L-cysteinato(2−)-κ4S,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-μ-sulfide species.
