Materials Data on CoSnO3 by Materials Project
CoSnO3 is Ilmenite structured and crystallizes in the trigonal R-3 space group. The structure is three-dimensional. Co2+ is bonded to six equivalent O2- atoms to form distorted CoO6 octahedra that share corners with nine equivalent SnO6 octahedra, edges with three equivalent CoO6 octahedra, and a faceface with one SnO6 octahedra. The corner-sharing octahedra tilt angles range from 47–62°. There are three shorter (2.08 Å) and three longer (2.24 Å) Co–O bond lengths. Sn4+ is bonded to six equivalent O2- atoms to form SnO6 octahedra that share corners with nine equivalent CoO6 octahedra, edges with three equivalent SnO6 octahedra, and a faceface with one CoO6 octahedra. The corner-sharing octahedra tilt angles range from 47–62°. There are three shorter (2.06 Å) and three longer (2.16 Å) Sn–O bond lengths. O2- is bonded to two equivalent Co2+ and two equivalent Sn4+ atoms to form a mixture of distorted edge and corner-sharing OCo2Sn2 trigonal pyramids.
