摘要:
A stingray pattern is adopted by Ba2Ag8S7. Crystals of this compound were grown in a two-electrode chemical cell from a BaS3/ethylenediamine solution. In the pseudo-one-dimensional structure columns of ∞/1[Ag8S7] (shown in the picture) are stacked head-to-tail to create voids where the barium atoms reside. The coexistence of S2- and S22- indicates a reductive decomposition [Eq. (1)].
