PaPtTl2 is Heusler structured and crystallizes in the trigonal R3m space group. Pa(1) is bonded in a 5-coordinate geometry to three equivalent Pt(1), one Tl(1), and one Tl(2) atom. All Pa(1)-Pt(1) bond lengths are 3.10 Å. The Pa(1)-Tl(1) bond length is 2.58 Å. The Pa(1)-Tl(2) bond length is 2.58 Å. Pt(1) is bonded in a 10-coordinate geometry to three equivalent Pa(1), three equivalent Tl(2), and four equivalent Tl(1) atoms. All Pt(1)-Tl(2) bond lengths are 2.98 Å. There is one shorter (2.58 Å) and three longer (3.32 Å) Pt(1)-Tl(1) bond lengths. There are two inequivalent Tl sites. In the first Tl site, Tl(1) is bonded in a 2-coordinate geometry to one Pa(1) and four equivalent Pt(1) atoms. In the second Tl site, Tl(2) is bonded in a 4-coordinate geometry to one Pa(1) and three equivalent Pt(1) atoms.
