The title compound, potassium diniobium vanadium phospho-rus deca-sulfide, KNb(1.75)V(0.25)PS(10), was obtained by reaction of the elements with a eutectic mixture of KCl/LiCl. It is isostructural with the quaternary KNb(2)PS(10), but the Nb sites are occupied by statistically disordered Nb (87.5%) and V (12.5%) atoms. The structure is composed of anionic (∞) (1)M(2)PS(10) chains (M = Nb/V) separated from each other by K(+) ions. The chain is composed of [MS(8)] distorted bicapped trigonal prisms and [PS(4)] tetra-hedra. There are no inter-chain bonding inter-actions. The crystal used for the X-ray analysis was a racemic twin.
标题化合物二铌钒磷钾十硫化物（KNb₁.₇₅V₀.₂₅PS₁₀）是通过元素与KCl/LiCl的低共熔混合物反应制得的。它与四元化合物KNb₂PS₁₀同构，但铌位点被统计无序的铌（87.5%）和钒（12.5%）原子占据。该结构由阴离子（∞）（1）[M₂PS₁₀]⁻链（M = Nb/V）组成，这些链通过K⁺离子彼此分隔。该链由[MS₈]扭曲的双帽三棱柱和[PS₄]四面体组成。不存在链间键合相互作用。用于X射线分析的晶体是一个外消旋孪晶。
