Materials Data on SrCa3(RuO3)4 by Materials Project
SrCa3(RuO3)4 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic Pm space group. The structure is three-dimensional. Sr2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Sr–O bond distances ranging from 2.44–2.76 Å. There are three inequivalent Ca2+ sites. In the first Ca2+ site, Ca2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.32–2.75 Å. In the second Ca2+ site, Ca2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.34–2.69 Å. In the third Ca2+ site, Ca2+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of Ca–O bond distances ranging from 2.33–2.69 Å. There are two inequivalent Ru4+ sites. In the first Ru4+ site, Ru4+ is bonded to six O2- atoms to form corner-sharing RuO6 octahedra. The corner-sharing octahedra tilt angles range from 23–31°. There are a spread of Ru–O bond distances ranging from 2.00–2.04 Å. In the second Ru4+ site, Ru4+ is bonded to six O2- atoms to form corner-sharing RuO6 octahedra. The corner-sharing octahedra tilt angles range from 26–31°. There are a spread of Ru–O bond distances ranging from 2.00–2.04 Å. There are eight inequivalent O2- sites. In the first O2- site, O2- is bonded in a 5-coordinate geometry to one Sr2+, two Ca2+, and two Ru4+ atoms. In the second O2- site, O2- is bonded in a 5-coordinate geometry to one Sr2+, two Ca2+, and two Ru4+ atoms. In the third O2- site, O2- is bonded in a 5-coordinate geometry to three Ca2+ and two Ru4+ atoms. In the fourth O2- site, O2- is bonded in a 5-coordinate geometry to one Sr2+, two Ca2+, and two Ru4+ atoms. In the fifth O2- site, O2- is bonded in a 4-coordinate geometry to one Sr2+, one Ca2+, and two equivalent Ru4+ atoms. In the sixth O2- site, O2- is bonded in a 4-coordinate geometry to one Sr2+, one Ca2+, and two equivalent Ru4+ atoms. In the seventh O2- site, O2- is bonded to two Ca2+ and two equivalent Ru4+ atoms to form distorted corner-sharing OCa2Ru2 tetrahedra. In the eighth O2- site, O2- is bonded to two Ca2+ and two equivalent Ru4+ atoms to form distorted corner-sharing OCa2Ru2 tetrahedra.
