Materials Data on Ca3Ga2(FeO5)2 by Materials Project
Abstract
Ca3Ga2(FeO5)2 crystallizes in the monoclinic Pc space group. The structure is three-dimensional. there are three inequivalent Ca sites. In the first Ca site, Ca is bonded in a 7-coordinate geometry to seven O atoms. There are a spread of Ca–O bond distances ranging from 2.23–2.55 Å. In the second Ca site, Ca is bonded in a 7-coordinate geometry to seven O atoms. There are a spread of Ca–O bond distances ranging from 2.26–2.66 Å. In the third Ca site, Ca is bonded in a 7-coordinate geometry to seven O atoms. There are a spread of Ca–O bond distances ranging from 2.39–2.63 Å. There are two inequivalent Fe sites. In the first Fe site, Fe is bonded to six O atoms to form FeO6 octahedra that share corners with four equivalent FeO6 octahedra and corners with two GaO4 tetrahedra. The corner-sharing octahedra tilt angles range from 8–23°. There are a spread of Fe–O bond distances ranging from 1.89–2.23 Å. In the second Fe site, Fe is bonded to six O atoms to form FeO6 octahedra that share corners with four equivalent FeO6 octahedra and corners with two GaO4 tetrahedra. The corner-sharing octahedra tilt angles range from 8–23°. There are a spreadmore »
