The compound described by Y4Co3 crystallizes in the trigonal P-3 space group. There are two inequivalent Y sites. In the first Y site, Y(1) is bonded in a 4-coordinate geometry to one Co(3) and three equivalent Co(2) atoms. In the second Y site, Y(2) is bonded in a 7-coordinate geometry to two equivalent Co(1) and five equivalent Co(2) atoms. There are three inequivalent Co sites. In the first Co site, Co(1) is bonded in a 9-coordinate geometry to six equivalent Y(2) and three equivalent Co(2) atoms. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to three equivalent Y(1), five equivalent Y(2), and one Co(1) atom. In the third Co site, Co(3) is bonded in a 6-coordinate geometry to six equivalent Y(1) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
