The crystal structure described by RhSn2 crystallizes in the tetragonal I4mm space group. There are three inequivalent Rh sites. In the first Rh site, Rh(1) is bonded in a 9-coordinate geometry to one Rh(3), four equivalent Sn(1), and four equivalent Sn(2) atoms. In the second Rh site, Rh(2) is bonded in a distorted single-bond geometry to one Rh(3) and four equivalent Sn(1) atoms. In the third Rh site, Rh(3) is bonded in a linear geometry to one Rh(1) and one Rh(2) atom. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded in a 8-coordinate geometry to two equivalent Rh(1), two equivalent Rh(2), and four equivalent Sn(2) atoms. In the second Sn site, Sn(2) is bonded in a 6-coordinate geometry to one Rh(1), two equivalent Sn(1), and three equivalent Sn(2) atoms. is represented by the CIF card [CIF]
