Title: Materials Data on Na2B4O11 by Materials Project

Abstract

(NaB2O5)4O2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional and consists of two hydrogen peroxide molecules and one NaB2O5 framework. In the NaB2O5 framework, there are two inequivalent Na sites. In the first Na site, Na is bonded in a 5-coordinate geometry to five O atoms. There are a spread of Na–O bond distances ranging from 2.30–2.59 Å. In the second Na site, Na is bonded in a 5-coordinate geometry to five O atoms. There are a spread of Na–O bond distances ranging from 2.27–2.57 Å. There are four inequivalent B sites. In the first B site, B is bonded in a trigonal planar geometry to three O atoms. All B–O bond lengths are 1.38 Å. In the second B site, B is bonded to four O atoms to form corner-sharing BO4 tetrahedra. There are a spread of B–O bond distances ranging from 1.45–1.50 Å. In the third B site, B is bonded to four O atoms to form corner-sharing BO4 tetrahedra. There are a spread of B–O bond distances ranging from 1.45–1.49 Å. In the fourth B site, B is bonded in a trigonal planar geometry to three O atoms. There are a spread of B–Omore » bond distances ranging from 1.36–1.39 Å. There are ten inequivalent O sites. In the first O site, O is bonded in a distorted trigonal planar geometry to one Na and two B atoms. In the second O site, O is bonded in a bent 150 degrees geometry to one Na and one O atom. The O–O bond length is 1.24 Å. In the third O site, O is bonded in a 4-coordinate geometry to two Na and two B atoms. In the fourth O site, O is bonded in a bent 120 degrees geometry to two B atoms. In the fifth O site, O is bonded in a distorted T-shaped geometry to two Na and one B atom. In the sixth O site, O is bonded in a distorted bent 150 degrees geometry to one Na and one B atom. In the seventh O site, O is bonded in a water-like geometry to one Na and one O atom. In the eighth O site, O is bonded in a bent 120 degrees geometry to two B atoms. In the ninth O site, O is bonded in a bent 120 degrees geometry to two B atoms. In the tenth O site, O is bonded in a distorted bent 120 degrees geometry to two Na and two B atoms.« less
