The compound described by HoCoSn2 crystallizes in the orthorhombic Cmcm space group. Ho(1) is bonded in a 10-coordinate geometry to four equivalent Co(1), two equivalent Sn(1), and four equivalent Sn(2) atoms. Co(1) is bonded in a distorted body-centered cubic geometry to four equivalent Ho(1) and four equivalent Sn(2) atoms. There are two inequivalent Sn sites. In the first Sn site, Sn(1) is bonded to two equivalent Ho(1) and two equivalent Sn(1) atoms to form distorted corner-sharing SnHo2Sn2 tetrahedra. In the second Sn site, Sn(2) is bonded in a 8-coordinate geometry to four equivalent Ho(1) and four equivalent Co(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
