Materials Data on La2MnGaO6 by Materials Project

Abstract

La2MnGaO6 is Orthorhombic Perovskite-derived structured and crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. La3+ is bonded in a 8-coordinate geometry to eight O2- atoms. There are a spread of La–O bond distances ranging from 2.37–2.94 Å. Mn3+ is bonded to six O2- atoms to form MnO6 octahedra that share corners with six equivalent GaO6 octahedra. The corner-sharing octahedral tilt angles are 26°. There are a spread of Mn–O bond distances ranging from 1.96–2.22 Å. Ga3+ is bonded to six O2- atoms to form GaO6 octahedra that share corners with six equivalent MnO6 octahedra. The corner-sharing octahedral tilt angles are 26°. There are a spread of Ga–O bond distances ranging from 1.96–2.06 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a 4-coordinate geometry to two equivalent La3+, one Mn3+, and one Ga3+ atom. In the second O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent La3+, one Mn3+, and one Ga3+ atom. In the third O2- site, O2- is bonded in a 5-coordinate geometry to three equivalent La3+, one Mn3+, and one Ga3+ atom.
