Materials Data on K2Ca5S6O25 by Materials Project
Abstract
K2Ca5S6O25 crystallizes in the monoclinic C2/c space group. The structure is three-dimensional. K is bonded in a 8-coordinate geometry to eight O atoms. There are a spread of K–O bond distances ranging from 2.78–3.07 Å. There are three inequivalent Ca sites. In the first Ca site, Ca is bonded in a 9-coordinate geometry to nine O atoms. There are a spread of Ca–O bond distances ranging from 2.45–2.71 Å. In the second Ca site, Ca is bonded to eight O atoms to form distorted CaO8 hexagonal bipyramids that share corners with four SO4 tetrahedra, edges with two equivalent CaO8 hexagonal bipyramids, and edges with two SO4 tetrahedra. There are a spread of Ca–O bond distances ranging from 2.40–2.62 Å. In the third Ca site, Ca is bonded in a 9-coordinate geometry to nine O atoms. There are a spread of Ca–O bond distances ranging from 2.41–2.67 Å. There are three inequivalent S sites. In the first S site, S is bonded to four O atoms to form SO4 tetrahedra that share corners with two equivalent CaO8 hexagonal bipyramids. There are a spread of S–O bond distances ranging from 1.48–1.50 Å. In the second S site, S is bonded to fourmore »
