CrCoPtPb crystallizes in the trigonal R3m space group. Cr(1) is bonded in a 11-coordinate geometry to four equivalent Co(1), three equivalent Pt(1), and four equivalent Pb(1) atoms. There is one shorter (2.28 Å) and three longer (2.97 Å) Cr(1)-Co(1) bond lengths. All Cr(1)-Pt(1) bond lengths are 2.72 Å. There is one shorter (2.17 Å) and three longer (3.02 Å) Cr(1)-Pb(1) bond lengths. Co(1) is bonded in a 11-coordinate geometry to four equivalent Cr(1), four equivalent Pt(1), and three equivalent Pb(1) atoms. There is one shorter (2.17 Å) and three longer (3.02 Å) Co(1)-Pt(1) bond lengths. All Co(1)-Pb(1) bond lengths are 2.72 Å. Pt(1) is bonded in a 1-coordinate geometry to three equivalent Cr(1) and four equivalent Co(1) atoms. Pb(1) is bonded in a distorted single-bond geometry to four equivalent Cr(1) and three equivalent Co(1) atoms.
