Materials Data on CrPO10 by Materials Project

Abstract

CrO6PO4 is Silicon tetrafluoride-derived structured and crystallizes in the monoclinic Cc space group. The structure is zero-dimensional and consists of eight phosphoric acid molecules and eight CrO6 clusters. In each CrO6 cluster, Cr is bonded in a tetrahedral geometry to four O atoms. There are a spread of Cr–O bond distances ranging from 1.62–1.75 Å. There are six inequivalent O sites. In the first O site, O is bonded in a single-bond geometry to one Cr atom. In the second O site, O is bonded in a bent 120 degrees geometry to two O atoms. There is one shorter (1.21 Å) and one longer (1.77 Å) O–O bond length. In the third O site, O is bonded in a single-bond geometry to one Cr and one O atom. In the fourth O site, O is bonded in a single-bond geometry to one Cr atom. In the fifth O site, O is bonded in a single-bond geometry to one O atom. In the sixth O site, O is bonded in a single-bond geometry to one Cr atom.
