Y3Co is Cementite structured and crystallizes in the monoclinic P2_1 space group. There are six inequivalent Y sites. In the first Y site, Y(1) is bonded in a distorted bent 150 degrees geometry to one Co(1) and one Co(2) atom. In the second Y site, Y(2) is bonded in a distorted bent 150 degrees geometry to one Co(1) and one Co(2) atom. In the third Y site, Y(3) is bonded in a 2-coordinate geometry to one Co(1) and two equivalent Co(2) atoms. In the fourth Y site, Y(4) is bonded in a distorted water-like geometry to one Co(2) and two equivalent Co(1) atoms. In the fifth Y site, Y(5) is bonded in a 3-coordinate geometry to one Co(2) and two equivalent Co(1) atoms. In the sixth Y site, Y(6) is bonded in a 2-coordinate geometry to one Co(1) and two equivalent Co(2) atoms. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 8-coordinate geometry to one Y(1), one Y(2), one Y(3), one Y(6), two equivalent Y(4), and two equivalent Y(5) atoms. In the second Co site, Co(2) is bonded in a 8-coordinate geometry to one Y(1), one Y(2), one Y(4), one Y(5), two equivalent Y(3), and two equivalent Y(6) atoms.
