Materials Data on MnAlO3 by Materials Project

Abstract

MnAlO3 crystallizes in the triclinic P-1 space group. The structure is three-dimensional. Mn3+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Mn–O bond distances ranging from 1.78–2.55 Å. Al3+ is bonded in a distorted bent 150 degrees geometry to three O2- atoms. There are a spread of Al–O bond distances ranging from 1.14–2.49 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted bent 120 degrees geometry to two equivalent Mn3+ and one Al3+ atom. In the second O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Mn3+ and one Al3+ atom. In the third O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Mn3+ and one Al3+ atom.
