The structure described by Co2SnO4 is Spinel-like structured and crystallizes in the orthorhombic Imma space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded to two equivalent O(1) and two equivalent O(2) atoms to form CoO4 tetrahedra that share corners with six equivalent Co(2)O6 octahedra and corners with six equivalent Sn(1)O6 octahedra. The corner-sharing octahedral tilt angles range from 55-59°. In the second Co site, Co(2) is bonded to two equivalent O(1) and four equivalent O(2) atoms to form CoO6 octahedra that share corners with six equivalent Co(1)O4 tetrahedra, edges with two equivalent Co(2)O6 octahedra, and edges with four equivalent Sn(1)O6 octahedra. Sn(1) is bonded to two equivalent O(2) and four equivalent O(1) atoms to form SnO6 octahedra that share corners with six equivalent Co(1)O4 tetrahedra, edges with two equivalent Sn(1)O6 octahedra, and edges with four equivalent Co(2)O6 octahedra. There are two inequivalent O sites. In the first O site, O(1) is bonded in a distorted rectangular see-saw-like geometry to one Co(1), one Co(2), and two equivalent Sn(1) atoms. In the second O site, O(2) is bonded to one Co(1), two equivalent Co(2), and one Sn(1) atom to form a mixture of distorted corner and edge-sharing OCo3Sn trigonal pyramids. is represented by the CIF file [CIF]
