Co2PtTl crystallizes in the monoclinic Cm space group. There are two inequivalent Co sites. In the first Co site, Co(1) is bonded in a 5-coordinate geometry to one Co(2) and four equivalent Pt(1) atoms. The Co(1)-Co(2) bond length is 2.86 Å. There are a spread of Co(1)-Pt(1) bond distances ranging from 2.20-2.80 Å. In the second Co site, Co(2) is bonded in a 5-coordinate geometry to one Co(1) and four equivalent Tl(1) atoms. There are a spread of Co(2)-Tl(1) bond distances ranging from 2.51-3.05 Å. Pt(1) is bonded in a single-bond geometry to four equivalent Co(1) and one Tl(1) atom. The Pt(1)-Tl(1) bond length is 0.52 Å. Tl(1) is bonded in a single-bond geometry to four equivalent Co(2) and one Pt(1) atom.
