Abstract

Fe3(GeO4)2 crystallizes in the monoclinic P2_1/c space group. The structure is three-dimensional. there are three inequivalent Fe+2.67+ sites. In the first Fe+2.67+ site, Fe+2.67+ is bonded to six O2- atoms to form FeO6 octahedra that share corners with six GeO4 tetrahedra and edges with four FeO6 octahedra. There are a spread of Fe–O bond distances ranging from 2.09–2.25 Å. In the second Fe+2.67+ site, Fe+2.67+ is bonded to six O2- atoms to form FeO6 octahedra that share a cornercorner with one FeO6 octahedra, corners with four GeO4 tetrahedra, and edges with five FeO6 octahedra. The corner-sharing octahedral tilt angles are 20°. There are a spread of Fe–O bond distances ranging from 2.00–2.21 Å. In the third Fe+2.67+ site, Fe+2.67+ is bonded to six O2- atoms to form FeO6 octahedra that share a cornercorner with one FeO6 octahedra, corners with five GeO4 tetrahedra, and edges with four FeO6 octahedra. The corner-sharing octahedral tilt angles are 20°. There are a spread of Fe–O bond distances ranging from 1.99–2.09 Å. There are two inequivalent Ge4+ sites. In the first Ge4+ site, Ge4+ is bonded to four O2- atoms to form GeO4 tetrahedra that share corners with seven FeO6 octahedra and a cornercorner withmore »« less
