Title: Materials Data on Na2GePCO7 by Materials Project

Abstract

Na2GeCPO7 crystallizes in the monoclinic P2_1/m space group. The structure is three-dimensional. Na1+ is bonded in a 6-coordinate geometry to six O2- atoms. There are a spread of Na–O bond distances ranging from 2.24–2.55 Å. Ge4+ is bonded to six O2- atoms to form GeO6 octahedra that share corners with four equivalent PO4 tetrahedra. There are a spread of Ge–O bond distances ranging from 2.03–2.37 Å. C3+ is bonded in a trigonal planar geometry to three O2- atoms. There are a spread of C–O bond distances ranging from 1.25–1.33 Å. P5+ is bonded to four O2- atoms to form PO4 tetrahedra that share corners with four equivalent GeO6 octahedra. The corner-sharing octahedra tilt angles range from 43–58°. There are a spread of P–O bond distances ranging from 1.55–1.57 Å. There are six inequivalent O2- sites. In the first O2- site, O2- is bonded in a 3-coordinate geometry to two equivalent Na1+ and one C3+ atom. In the second O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two equivalent Na1+, one Ge4+, and one C3+ atom. In the third O2- site, O2- is bonded in a distorted trigonal pyramidal geometry to two equivalent Na1+, one Ge4+, andmore » one C3+ atom. In the fourth O2- site, O2- is bonded in a 1-coordinate geometry to one Na1+, one Ge4+, and one P5+ atom. In the fifth O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two equivalent Na1+, one Ge4+, and one P5+ atom. In the sixth O2- site, O2- is bonded in a 1-coordinate geometry to two equivalent Na1+, one Ge4+, and one P5+ atom.« less
