Materials Data on SrCa3V4O12 by Materials Project
SrCa3V4O12 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic Pm space group. The structure is three-dimensional. Sr2+ is bonded in a 12-coordinate geometry to ten O2- atoms. There are a spread of Sr–O bond distances ranging from 2.50–2.93 Å. There are three inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded in a 4-coordinate geometry to six O2- atoms. There are a spread of Ca–O bond distances ranging from 2.34–2.72 Å. In the second 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 2.38–2.86 Å. In the third Ca2+ site, Ca2+ is bonded in a 12-coordinate geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.33–2.76 Å. There are two inequivalent V4+ sites. In the first V4+ site, V4+ is bonded to six O2- atoms to form corner-sharing VO6 octahedra. The corner-sharing octahedra tilt angles range from 18–26°. There are a spread of V–O bond distances ranging from 1.87–2.03 Å. In the second V4+ site, V4+ is bonded to six O2- atoms to form corner-sharing VO6 octahedra.
