The structure described by CaMgSn crystallizes in the orthorhombic Pnma space group. Ca(1) is bonded in a 11-coordinate geometry to six equivalent Mg(1) and five equivalent Sn(1) atoms. Mg(1) is bonded to six equivalent Ca(1) and four equivalent Sn(1) atoms to form a mixture of distorted face, corner, and edge-sharing MgCa6Sn4 tetrahedra. Sn(1) is bonded in a 9-coordinate geometry to five equivalent Ca(1) and four equivalent Mg(1) atoms. is represented by the CIF file [CIF]
