Materials Data on Ca10V6O25 by Materials Project
Ca10V6O25 crystallizes in the trigonal P-3 space group. The structure is three-dimensional. there are three inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Ca–O bond distances ranging from 2.28–2.84 Å. In the second Ca2+ site, Ca2+ is bonded to six O2- atoms to form distorted CaO6 pentagonal pyramids that share corners with six equivalent VO4 tetrahedra. There are three shorter (2.35 Å) and three longer (2.41 Å) Ca–O bond lengths. In the third Ca2+ site, Ca2+ is bonded in a 9-coordinate geometry to nine O2- atoms. There are a spread of Ca–O bond distances ranging from 2.39–2.82 Å. V5+ is bonded to four O2- atoms to form VO4 tetrahedra that share corners with two equivalent CaO6 pentagonal pyramids. There are a spread of V–O bond distances ranging from 1.71–1.77 Å. There are five inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two Ca2+ and one V5+ atom. In the second O2- site, O2- is bonded in an octahedral geometry to six equivalent Ca2+ atoms. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Ca2+ and one V5+ atom. In the fourth O2- site, O2- is bonded in a 4-coordinate geometry to three Ca2+ and one V5+ atom. In the fifth O2- site, O2- is bonded in a 1-coordinate geometry to three Ca2+ and one V5+ atom.
