Title: Materials Data on Co2SiO4 by Materials Project

Abstract

Co2SiO4 is Ilmenite-like structured and crystallizes in the triclinic P1 space group. The structure is three-dimensional. there are eight inequivalent Co2+ sites. In the first Co2+ site, Co2+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with eight CoO6 octahedra, corners with four SiO4 tetrahedra, edges with two CoO6 octahedra, and an edgeedge with one SiO4 tetrahedra. The corner-sharing octahedra tilt angles range from 50–62°. There are a spread of Co–O bond distances ranging from 2.09–2.26 Å. In the second Co2+ site, Co2+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with four CoO6 octahedra, corners with two SiO4 tetrahedra, edges with four CoO6 octahedra, and edges with two SiO4 tetrahedra.
