Materials Data on NaSbO7 by Materials Project

Abstract

NaSbO5O2 crystallizes in the orthorhombic Cmc2_1 space group. The structure is three-dimensional and consists of four hydrogen peroxide molecules and one NaSbO5 framework. In the NaSbO5 framework, Na is bonded in a 4-coordinate geometry to four equivalent O atoms. There are two shorter (2.41 Å) and two longer (2.69 Å) Na–O bond lengths. Sb is bonded in a 5-coordinate geometry to five O atoms. There are a spread of Sb–O bond distances ranging from 1.87–2.45 Å. There are three inequivalent O sites. In the first O site, O is bonded in a distorted trigonal non-coplanar geometry to one Sb and two equivalent O atoms. Both O–O bond lengths are 1.46 Å. In the second O site, O is bonded in a 3-coordinate geometry to two equivalent Na and one Sb atom. In the third O site, O is bonded in an L-shaped geometry to one Sb and one O atom.
