MnPt4Tl crystallizes in the trigonal R3m space group. Mn(1) is bonded in a distorted single-bond geometry to three equivalent Pt(1), three equivalent Pt(2), and one Tl(1) atom. All Mn(1)-Pt(1) bond lengths are 3.04 Å. All Mn(1)-Pt(2) bond lengths are 3.09 Å. The Mn(1)-Tl(1) bond length is 1.60 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(2) is bonded in a 6-coordinate geometry to three equivalent Mn(1) and three equivalent Pt(1) atoms. All Pt(2)-Pt(1) bond lengths are 1.10 Å. In the second Pt site, Pt(1) is bonded in a 5-coordinate geometry to one Mn(1), one Pt(2), two equivalent Pt(1), and one Tl(1) atom. Both Pt(1)-Pt(1) bond lengths are 0.63 Å. The Pt(1)-Tl(1) bond length is 1.39 Å. Tl(1) is bonded in a distorted rectangular see-saw-like geometry to one Mn(1) and three equivalent Pt(1) atoms.
