ZrRhCoPt crystallizes in the trigonal R3m space group. Zr(1) is bonded in a distorted single-bond geometry to three equivalent Rh(1), one Co(1), and three equivalent Pt(1) atoms. All Zr(1)-Rh(1) bond lengths are 2.74 Å. The Zr(1)-Co(1) bond length is 1.85 Å. All Zr(1)-Pt(1) bond lengths are 2.74 Å. Rh(1) is bonded in a 8-coordinate geometry to three equivalent Zr(1), four equivalent Co(1), and one Pt(1) atom. There is one shorter (2.72 Å) and three longer (2.75 Å) Rh(1)-Co(1) bond lengths. The Rh(1)-Pt(1) bond length is 1.85 Å. Co(1) is bonded in a distorted single-bond geometry to one Zr(1), four equivalent Rh(1), and three equivalent Pt(1) atoms.
