The title compound catena-poly[potassium [tri-μ-disulfido-μ-tetra-thiophos-pha-to-di[niobate(IV)/tantalate(IV)(0.885/0.115)]]], has been obtained through the reaction of the elements with KCl. The title compound is isostructural with KNb2PS10, with the Nb sites occupied by statistically disordered Nb (88.5%) and Ta (11.5%) atoms. The structure is composed of anionic ∞ (1)M 2PS10 chains along [100] (M = Nb/Ta) and K(+) ions. This chain is built up from distorted bicapped trigonal prisms [MS8] and [PS4] tetra-hedra. There are no inter-chain bonding inter-actions, except for electrostatic and van der Waals forces. The S2 (2-) and S(2-) anionic species and the M (4+)-M (4+) pair [M-M = 2.8939 (3) Å] are observed. The classical charge balance is represented by [K(+)][M (4+)]2[PS4 (3-)][S2 (2-)]3.
标题化合物链状聚[钾[三-μ-二硫代-μ-四硫代磷酸根二[铌酸盐(IV)/钽酸盐(IV)(0.885/0.115)]]]，是通过元素与氯化钾反应制得的。该标题化合物与KNb2PS10同构，其中铌位点被统计无序的铌(88.5%)和钽(11.5%)原子占据。结构由沿[100]方向的阴离子∞(1)M2PS10链和K(+)离子组成。这条链由扭曲的双帽三棱柱[MS8]和[PS4]四面体构成。除了静电和范德华力外，不存在链间键合相互作用。观察到S2(2-)和S(2-)阴离子物种以及M(4+)-M(4+)对[M-M = 2.8939 (3) Å]。经典的电荷平衡由[K(+)][M(4+)]2[PS4(3-)][S2(2-)]3表示。
