The material described by Co3Sn2 crystallizes in the orthorhombic Pnma space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 11-coordinate geometry to six equivalent Co(2), two equivalent Sn(2), and three equivalent Sn(1) atoms. In the second Co site, Co(2) is bonded in a 11-coordinate geometry to two equivalent Co(2), three equivalent Co(1), three equivalent Sn(1), and three equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(2) is bonded in a 6-coordinate geometry to two equivalent Co(1) and six equivalent Co(2) atoms. In the second Sn site, Sn(1) is bonded in a 9-coordinate geometry to three equivalent Co(1) and six equivalent Co(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
