Title: Materials Data on NaSmGeO4 by Materials Project

Abstract

NaSmGeO4 is Hausmannite-derived structured and crystallizes in the orthorhombic Pnma space group. The structure is three-dimensional. Na1+ is bonded to six O2- atoms to form NaO6 octahedra that share corners with four equivalent SmO6 octahedra, corners with two equivalent GeO4 tetrahedra, edges with two equivalent NaO6 octahedra, edges with two equivalent SmO6 octahedra, and edges with two equivalent GeO4 tetrahedra. The corner-sharing octahedra tilt angles range from 61–67°. There are a spread of Na–O bond distances ranging from 2.44–2.56 Å. Sm3+ is bonded to six O2- atoms to form SmO6 octahedra that share corners with four equivalent NaO6 octahedra, corners with four equivalent SmO6 octahedra, corners with four equivalent GeO4 tetrahedra, edges with two equivalent NaO6 octahedra, and an edgeedge with one GeO4 tetrahedra. The corner-sharing octahedra tilt angles range from 50–67°. There are a spread of Sm–O bond distances ranging from 2.29–2.43 Å. Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with two equivalent NaO6 octahedra, corners with four equivalent SmO6 octahedra, an edgeedge with one SmO6 octahedra, and edges with two equivalent NaO6 octahedra. The corner-sharing octahedra tilt angles range from 47–62°. There are a spread of Ge–O bond distances ranging frommore » 1.75–1.81 Å. There are three inequivalent O2- sites. In the first O2- site, O2- is bonded in a rectangular see-saw-like geometry to two equivalent Na1+, one Sm3+, and one Ge4+ atom. In the second O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to one Na1+, two equivalent Sm3+, and one Ge4+ atom. In the third O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two equivalent Na1+, one Sm3+, and one Ge4+ atom.« less
