The compound described by UCo2Sn crystallizes in the orthorhombic Pnma space group. U(1) is bonded in a 6-coordinate geometry to four equivalent Co(1), four equivalent Co(2), and five equivalent Sn(1) atoms. There are two inequivalent Co sites. In the first Co site, Co(2) is bonded in a 8-coordinate geometry to four equivalent U(1) and four equivalent Sn(1) atoms. In the second Co site, Co(1) is bonded in a 7-coordinate geometry to four equivalent U(1) and three equivalent Sn(1) atoms. Sn(1) is bonded in a 12-coordinate geometry to five equivalent U(1), three equivalent Co(1), and four equivalent Co(2) atoms. is represented by the CIF card [CIF]
