W3PtTl crystallizes in the trigonal R3m space group. W(1) is bonded in a 5-coordinate geometry to two equivalent Pt(1) and three equivalent Tl(1) atoms. There is one shorter (2.01 Å) and one longer (2.82 Å) W(1)-Pt(1) bond length. There is one shorter (2.85 Å) and two longer (3.46 Å) W(1)-Tl(1) bond lengths. Pt(1) is bonded to six equivalent W(1) atoms to form distorted corner-sharing PtW6 octahedra. The corner-sharing octahedra are not tilted. Tl(1) is bonded in a 9-coordinate geometry to nine equivalent W(1) atoms.
