Materials Data on K3V(SO5)2 by Materials Project
K3VO2(SO4)2 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. there are three inequivalent K1+ sites. In the first K1+ site, K1+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of K–O bond distances ranging from 2.75–3.15 Å. In the second K1+ site, K1+ is bonded to seven O2- atoms to form KO7 pentagonal bipyramids that share corners with four SO4 tetrahedra and an edgeedge with one SO4 tetrahedra. There are a spread of K–O bond distances ranging from 2.73–3.02 Å. In the third K1+ site, K1+ is bonded in a 7-coordinate geometry to seven O2- atoms. There are a spread of K–O bond distances ranging from 2.88–3.01 Å. V5+ is bonded in a 4-coordinate geometry to six O2- atoms. There are a spread of V–O bond distances ranging from 1.66–2.54 Å. There are two inequivalent S6+ sites. In the first S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with two equivalent KO7 pentagonal bipyramids and an edgeedge with one KO7 pentagonal bipyramid. There are a spread of S–O bond distances ranging from 1.46–1.56 Å. In the second S6+ site, S6+ is bonded to four O2- atoms to form SO4 tetrahedra that share corners with two equivalent KO7 pentagonal bipyramids. There are a spread of S–O bond distances ranging from 1.46–1.57 Å. There are ten inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted water-like geometry to one K1+, one V5+, and one S6+ atom. In the second O2- site, O2- is bonded in a distorted single-bond geometry to two equivalent K1+, one V5+, and one S6+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two K1+, one V5+, and one S6+ atom. In the fourth O2- site, O2- is bonded in a distorted water-like geometry to two K1+, one V5+, and one S6+ atom. In the fifth O2- site, O2- is bonded in a distorted single-bond geometry to two K1+ and one S6+ atom. In the sixth O2- site, O2- is bonded in a distorted single-bond geometry to two K1+ and one V5+ atom. In the seventh O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one S6+ atom. In the eighth O2- site, O2- is bonded in a distorted single-bond geometry to two K1+ and one S6+ atom. In the ninth O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one S6+ atom. In the tenth O2- site, O2- is bonded in a distorted single-bond geometry to three K1+ and one V5+ atom.
