CoPt2Zn crystallizes in the monoclinic Cm space group. Co(1) is bonded in a 12-coordinate geometry to four equivalent Co(1), four equivalent Pt(1), and four equivalent Zn(1) atoms. All Co(1)-Co(1) bond lengths are 2.77 Å. There are a spread of Co(1)-Pt(1) bond distances ranging from 2.71-3.30 Å. There are a spread of Co(1)-Zn(1) bond distances ranging from 2.60-3.21 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 13-coordinate geometry to four equivalent Co(1), four equivalent Pt(1), four equivalent Pt(2), and one Zn(1) atom. All Pt(1)-Pt(1) bond lengths are 2.77 Å. There are a spread of Pt(1)-Pt(2) bond distances ranging from 2.24-2.92 Å. The Pt(1)-Zn(1) bond length is 2.97 Å. In the second Pt site, Pt(2) is bonded in a 1-coordinate geometry to four equivalent Pt(1) and one Zn(1) atom. The Pt(2)-Zn(1) bond length is 2.00 Å. Zn(1) is bonded in a 1-coordinate geometry to four equivalent Co(1), one Pt(1), and one Pt(2) atom.
