YCrCo4 crystallizes in the trigonal R3m space group. Y(1) is bonded in a 3-coordinate geometry to three equivalent Cr(1), three equivalent Co(1), and three equivalent Co(2) atoms. All Y(1)-Cr(1) bond lengths are 2.97 Å. All Y(1)-Co(1) bond lengths are 2.54 Å. All Y(1)-Co(2) bond lengths are 2.91 Å. Cr(1) is bonded in a 9-coordinate geometry to three equivalent Y(1), three equivalent Co(1), and three equivalent Co(2) atoms. All Cr(1)-Co(1) bond lengths are 2.77 Å. All Cr(1)-Co(2) bond lengths are 2.85 Å. There are two inequivalent Co sites. In the first Co site, Co(2) is bonded in a 9-coordinate geometry to three equivalent Y(1), three equivalent Cr(1), and three equivalent Co(1) atoms. All Co(2)-Co(1) bond lengths are 2.11 Å. In the second Co site, Co(1) is bonded in a 3-coordinate geometry to one Y(1), one Cr(1), one Co(2), and two equivalent Co(1) atoms. Both Co(1)-Co(1) bond lengths are 1.22 Å.
