title: A new quaternary thiophosphate, RbNb2(S2)3(PS4).
abstract: The structure of the new quaternary thiophosphate rubidium diniobium tris(disulfide) tetrathiophosphate, RbNb(2)(S2)(3)(PS4), is made up of one-dimensional (infinity)(1)[Nb(2)(S2)(3)(PS4)(-)] chains along the [101] direction, and these chains are separated from one another by Rb(+) ions. The chain is basically built up from [Nb(2)S(12)] units and tetrahedral [PS(4)] groups. The [Nb(2)S(12)] units are linked together to form a linear [Nb(2)S(9)] chain by sharing the S-S prism edge. Short and long Nb-Nb distances [2.888 (2) and 3.760 (2) A, respectively] alternate along the chain, and the anionic species S(2)(2-) and S(2-) are observed.
