Materials Data on NaGeO3 by Materials Project

Abstract

NaGeO3 is (Cubic) Perovskite structured and crystallizes in the cubic Pm-3m space group. The structure is three-dimensional. Na is bonded to twelve equivalent O atoms to form NaO12 cuboctahedra that share corners with twelve equivalent NaO12 cuboctahedra, faces with six equivalent NaO12 cuboctahedra, and faces with eight equivalent GeO6 octahedra. All Na–O bond lengths are 2.66 Å. Ge is bonded to six equivalent O atoms to form GeO6 octahedra that share corners with six equivalent GeO6 octahedra and faces with eight equivalent NaO12 cuboctahedra. The corner-sharing octahedral tilt angles are 0°. All Ge–O bond lengths are 1.88 Å. O is bonded to four equivalent Na and two equivalent Ge atoms to form a mixture of distorted face, edge, and corner-sharing ONa4Ge2 octahedra. The corner-sharing octahedra tilt angles range from 0–60°.
