Materials Data on ThMo2O9 by Materials Project

Abstract

ThMo2O9 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. Th is bonded in a 9-coordinate geometry to nine O atoms. There are a spread of Th–O bond distances ranging from 2.40–2.51 Å. There are two inequivalent Mo sites. In the first Mo site, Mo is bonded in a tetrahedral geometry to four O atoms. There are a spread of Mo–O bond distances ranging from 1.78–1.81 Å. In the second Mo site, Mo is bonded in a tetrahedral geometry to four O atoms. There is three shorter (1.79 Å) and one longer (1.81 Å) Mo–O bond length. There are nine inequivalent O sites. In the first O site, O is bonded in a distorted linear geometry to one Th and one Mo atom. In the second O site, O is bonded in a single-bond geometry to one Th atom. In the third O site, O is bonded in a distorted linear geometry to one Th and one Mo atom. In the fourth O site, O is bonded in a bent 150 degrees geometry to one Th and one Mo atom. In the fifth O site, O is bonded in a distorted bent 150 degrees geometry to one Th and one Mo atom. In the sixth O site, O is bonded in a distorted bent 150 degrees geometry to one Th and one Mo atom. In the seventh O site, O is bonded in a distorted bent 150 degrees geometry to one Th and one Mo atom. In the eighth O site, O is bonded in a distorted bent 150 degrees geometry to one Th and one Mo atom. In the ninth O site, O is bonded in a distorted bent 150 degrees geometry to one Th and one Mo atom.
