Title: Materials Data on Na2GeO9 by Materials Project

Abstract

Na2GeO9 crystallizes in the monoclinic P2_1 space group. The structure is three-dimensional. 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 2.33–2.68 Å. In the second Na site, Na is bonded in a 3-coordinate geometry to four O atoms. There are a spread of Na–O bond distances ranging from 2.24–2.93 Å. Ge is bonded in a distorted trigonal bipyramidal geometry to five O atoms. There are a spread of Ge–O bond distances ranging from 1.70–2.29 Å. There are nine inequivalent O sites. In the first O site, O is bonded in a water-like geometry to one Na and one Ge atom. In the second O site, O is bonded in a distorted trigonal planar geometry to one Na, one Ge, and one O atom. The O–O bond length is 1.49 Å. In the third O site, O is bonded in a trigonal non-coplanar geometry to two equivalent Na and one Ge atom. In the fourth O site, O is bonded in a 1-coordinate geometry to one Na, one Ge, and one O atom. The O–O bond lengthmore » is 1.33 Å. In the fifth O site, O is bonded in a distorted bent 120 degrees geometry to two O atoms. The O–O bond length is 1.32 Å. In the sixth O site, O is bonded in a bent 120 degrees geometry to one Na and one O atom. The O–O bond length is 1.24 Å. In the seventh O site, O is bonded in a single-bond geometry to one O atom. In the eighth O site, O is bonded in a distorted trigonal planar geometry to two equivalent Na and one O atom. In the ninth O site, O is bonded in a distorted trigonal non-coplanar geometry to one Na, one Ge, and one O atom.« less
