CoSnO3 is Ilmenite structured and crystallizes in the trigonal R-3 space group. Co(1) is bonded to six equivalent O(1) atoms to form distorted CoO6 octahedra that share corners with nine equivalent Sn(1)O6 octahedra, edges with three equivalent Co(1)O6 octahedra, and  a faceface with one Sn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 47-62°. Sn(1) is bonded to six equivalent O(1) atoms to form SnO6 octahedra that share corners with nine equivalent Co(1)O6 octahedra, edges with three equivalent Sn(1)O6 octahedra, and  a faceface with one Co(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 47-62°. O(1) is bonded to two equivalent Co(1) and two equivalent Sn(1) atoms to form a mixture of distorted corner and edge-sharing OCo2Sn2 trigonal pyramids.
