Materials Data on LaMoO5 by Materials Project
LaMoO5 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. La is bonded in a 8-coordinate geometry to eight O atoms. There are a spread of La–O bond distances ranging from 2.37–2.65 Å. Mo is bonded in a tetrahedral geometry to four O atoms. There are a spread of Mo–O bond distances ranging from 1.77–1.85 Å. There are five inequivalent O sites. In the first O site, O is bonded in a 3-coordinate geometry to two equivalent La and one O atom. The O–O bond length is 1.51 Å. In the second O site, O is bonded in a distorted trigonal planar geometry to two equivalent La and one Mo atom. In the third O site, O is bonded in a distorted trigonal planar geometry to two equivalent La and one Mo atom. In the fourth O site, O is bonded in a distorted bent 150 degrees geometry to one La and one Mo atom. In the fifth O site, O is bonded in a distorted bent 150 degrees geometry to one La and one Mo atom.
