Materials Data on Co2SnO4 by Materials Project
Co2SnO4 is Spinel-like structured and crystallizes in the orthorhombic Imma space group. The structure is three-dimensional. there are two inequivalent Co2+ sites. In the first Co2+ site, Co2+ is bonded to four O2- atoms to form CoO4 tetrahedra that share corners with six equivalent CoO6 octahedra and corners with six equivalent SnO6 octahedra. The corner-sharing octahedra tilt angles range from 56–60°. There are two shorter (2.02 Å) and two longer (2.04 Å) Co–O bond lengths. In the second Co2+ site, Co2+ is bonded to six O2- atoms to form CoO6 octahedra that share corners with six equivalent CoO4 tetrahedra, edges with two equivalent CoO6 octahedra, and edges with four equivalent SnO6 octahedra. There are four shorter (2.11 Å) and two longer (2.18 Å) Co–O bond lengths. Sn4+ is bonded to six O2- atoms to form SnO6 octahedra that share corners with six equivalent CoO4 tetrahedra, edges with two equivalent SnO6 octahedra, and edges with four equivalent CoO6 octahedra. There are two shorter (2.07 Å) and four longer (2.12 Å) Sn–O bond lengths. There are two inequivalent O2- sites. In the first O2- site, O2- is bonded in a distorted rectangular see-saw-like geometry to two Co2+ and two equivalent Sn4+ atoms. In the second O2- site, O2- is bonded to three Co2+ and one Sn4+ atom to form a mixture of distorted edge and corner-sharing OCo3Sn trigonal pyramids.
