Materials Data on Co2SiO4 by Materials Project
Abstract
Co2SiO4 crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. there are three inequivalent Co2+ sites. In the first Co2+ site, Co2+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with two equivalent CoO6 octahedra, corners with four equivalent SiO4 tetrahedra, and edges with seven CoO6 octahedra. The corner-sharing octahedral tilt angles are 14°. There are a spread of Co–O bond distances ranging from 2.09–2.16 Å. In the second Co2+ site, Co2+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with six equivalent SiO4 tetrahedra and edges with six CoO6 octahedra. There are a spread of Co–O bond distances ranging from 2.05–2.15 Å. In the third Co2+ site, Co2+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with six equivalent SiO4 tetrahedra and edges with six CoO6 octahedra. There are four shorter (2.10 Å) and two longer (2.13 Å) Co–O bond lengths. Si4+ is bonded to four O2- atoms to form SiO4 tetrahedra that share corners with ten CoO6 octahedra and a cornercorner with one SiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 45–61°. There are a spread of Si–O bond distancesmore »

In the first O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to three Co2+ and one Si4+ atom. In the second O2- site, O2- is bonded to five Co2+ atoms to form edge-sharing OCo5 square pyramids. In the third O2- site, O2- is bonded in a trigonal planar geometry to one Co2+ and two equivalent Si4+ atoms. In the fourth O2- site, O2- is bonded in a rectangular see-saw-like geometry to three Co2+ and one Si4+ atom.},
