The polymeric cluster compound [(tmenH(2))center dot(W2Ag2S8)center dot(tmen)center dot(H2O)](n) (tmen=N,N,N',N'-tetramethylethylenediamine)

The structure of the (W2Ag2S8)(2-) anion of the title cluster compound, catena-poly[N,N,N',N'-tetramethyl-ethylenediammonium bis(tungsten-di-mu-sulfido-silver-di-mu-sulfido) N,N,N',N'- tetramethylethylenediamine hydrate], {(C6H18N2)[W2Ag2S8].(C6H16N2). H2O}(n), can be described as a polymeric chain consisting of extended >AgS2W< fragments, In the chain, which has disordered W and Ag atoms, neighbouring fragments of this kind are alternately nearly perpendicular to each other. Water molecules are connected to the tmenH(2)(2+) cations and tmen molecules through hydrogen bonding.
