Abstract

NaGdGeO4 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 GdO6 octahedra, corners with two equivalent GeO4 tetrahedra, edges with two equivalent NaO6 octahedra, edges with two equivalent GdO6 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 2.43–2.56 Å. Gd3+ is bonded to six O2- atoms to form GdO6 octahedra that share corners with four equivalent NaO6 octahedra, corners with four equivalent GdO6 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 49–67°. There are a spread of Gd–O bond distances ranging from 2.27–2.40 Å. Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with two equivalent NaO6 octahedra, corners with four equivalent GdO6 octahedra, an edgeedge with one GdO6 octahedra, and edges with two equivalent NaO6 octahedra.
