The compound described by Y12Co5Bi crystallizes in the orthorhombic Immm space group. There are three inequivalent Y sites. In the first Y site, Y(1) is bonded in a 5-coordinate geometry to one Co(1), one Co(3), two equivalent Co(2), and one Bi(1) atom. In the second Y site, Y(2) is bonded in a 4-coordinate geometry to one Co(2), two equivalent Co(1), and one Bi(1) atom. In the third Y site, Y(3) is bonded in a 2-coordinate geometry to one Co(1), one Co(2), one Co(3), and one Bi(1) atom. There are three inequivalent Co sites. In the first Co site, Co(1) is bonded in a 9-coordinate geometry to two equivalent Y(1), two equivalent Y(3), four equivalent Y(2), and one Co(1) atom. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to two equivalent Y(2), two equivalent Y(3), four equivalent Y(1), and one Co(2) atom. In the third Co site, Co(3) is bonded in a distorted body-centered cubic geometry to four equivalent Y(1) and four equivalent Y(3) atoms. Bi(1) is bonded in a cuboctahedral geometry to four equivalent Y(1), four equivalent Y(2), and four equivalent Y(3) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
