YCo4Pt crystallizes in the trigonal R3m space group. Y(1) is bonded in a 10-coordinate geometry to three equivalent Co(1), three equivalent Co(2), and four equivalent Pt(1) atoms. All Y(1)-Co(1) bond lengths are 2.42 Å. All Y(1)-Co(2) bond lengths are 2.90 Å. There is one shorter (2.71 Å) and three longer (3.13 Å) Y(1)-Pt(1) bond lengths. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 4-coordinate geometry to one Y(1), one Co(2), two equivalent Co(1), and two equivalent Pt(1) atoms. The Co(1)-Co(2) bond length is 2.34 Å. Both Co(1)-Co(1) bond lengths are 1.35 Å. There is one shorter (2.53 Å) and one longer (2.68 Å) Co(1)-Pt(1) bond length. In the second Co site, Co(2) is bonded in a 9-coordinate geometry to three equivalent Y(1), three equivalent Co(1), and three equivalent Pt(1) atoms. All Co(2)-Pt(1) bond lengths are 2.94 Å. Pt(1) is bonded in a 13-coordinate geometry to four equivalent Y(1), three equivalent Co(2), and six equivalent Co(1) atoms.
