The material described by RhSn2 crystallizes in the orthorhombic Cmce space group. Rh(1) is bonded in a 8-coordinate geometry to four equivalent Sn(1) and four equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 4-coordinate geometry to four equivalent Rh(1) atoms. In the second Sn site, Sn(2) is bonded to four equivalent Rh(1) atoms to form a mixture of corner and edge-sharing SnRh4 tetrahedra. is represented by the Crystallographic Information File (CIF) [CIF]
