Materials Data on Cd3(P3O14)2 by Materials Project

Abstract

(Cd(PO4)2)3(O2)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional and consists of four hydrogen peroxide molecules and one Cd(PO4)2 framework. In the Cd(PO4)2 framework, there are two inequivalent Cd sites. In the first Cd site, Cd is bonded to four O atoms to form CdO4 tetrahedra that share corners with four PO4 tetrahedra. There are a spread of Cd–O bond distances ranging from 2.16–2.18 Å. In the second Cd site, Cd is bonded in a distorted square co-planar geometry to six O atoms. There are a spread of Cd–O bond distances ranging from 2.19–2.81 Å. There are three inequivalent P sites. In the first P site, P is bonded to four O atoms to form PO4 tetrahedra that share corners with two equivalent CdO4 tetrahedra and corners with two PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.49–1.62 Å. In the second P site, P is bonded to four O atoms to form PO4 tetrahedra that share corners with two equivalent CdO4 tetrahedra and corners with two PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.50–1.62 Å. In the third P site, P is bonded to four O atoms to form corner-sharing PO4 tetrahedra. There are a spread of P–O bond distances ranging from 1.50–1.64 Å. There are twelve inequivalent O sites. In the first O site, O is bonded in a distorted bent 120 degrees geometry to one Cd and one P atom. In the second O site, O is bonded in a distorted bent 150 degrees geometry to one Cd and one P atom. In the third O site, O is bonded in a single-bond geometry to one Cd atom. In the fourth O site, O is bonded in a bent 150 degrees geometry to one Cd and one P atom. In the fifth O site, O is bonded in a bent 150 degrees geometry to one Cd and one P atom. In the sixth O site, O is bonded in a bent 120 degrees geometry to two P atoms. In the seventh O site, O is bonded in a single-bond geometry to one P atom. In the eighth O site, O is bonded in a bent 120 degrees geometry to two P atoms. In the ninth O site, O is bonded in a distorted bent 120 degrees geometry to one Cd and one O atom. The O–O bond length is 1.24 Å. In the tenth O site, O is bonded in a single-bond geometry to one O atom. In the eleventh O site, O is bonded in a bent 120 degrees geometry to two P atoms. In the twelfth O site, O is bonded in a bent 150 degrees geometry to one Cd and one P atom.
