The Polymeric Cluster Compound [(tmenH₂).(W₂Ag₂S₈).(tmen).(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′-tetramethylenediammonium bis(tungsten-di-μ-sulfido-silver-di-μ-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 tmenH₂²⁺ cations and tmen molecules through hydrogen bonding.
