Abstract

KNb2PS10 crystallizes in the orthorhombic Pca2_1 space group. The structure is three-dimensional. K1+ is bonded in a 5-coordinate geometry to five S+1.60- atoms. There are a spread of K–S bond distances ranging from 3.34–3.81 Å. There are two inequivalent Nb5+ sites. In the first Nb5+ site, Nb5+ is bonded to eight S+1.60- atoms to form NbS8 hexagonal bipyramids that share an edgeedge with one PS4 tetrahedra and faces with two equivalent NbS8 hexagonal bipyramids. There are a spread of Nb–S bond distances ranging from 2.50–2.66 Å. In the second Nb5+ site, Nb5+ is bonded to eight S+1.60- atoms to form NbS8 hexagonal bipyramids that share an edgeedge with one PS4 tetrahedra and faces with two equivalent NbS8 hexagonal bipyramids. There are a spread of Nb–S bond distances ranging from 2.50–2.66 Å. P5+ is bonded to four S+1.60- atoms to form PS4 tetrahedra that share edges with two NbS8 hexagonal bipyramids. There are a spread of P–S bond distances ranging from 1.99–2.10 Å. There are ten inequivalent S+1.60- sites. In the first S+1.60- site, S+1.60- is bonded in a 3-coordinate geometry to two Nb5+ and one S+1.60- atom. The S–S bond length is 2.05 Å. In the second S+1.60- site, S+1.60-more »« less
