TiW2Pt crystallizes in the triclinic P1 space group. Ti(1) is bonded in a 5-coordinate geometry to one W(2), two equivalent W(1), and two equivalent Pt(1) atoms. The Ti(1)-W(2) bond length is 2.21 Å. There is one shorter (1.82 Å) and one longer (2.79 Å) Ti(1)-W(1) bond length. There is one shorter (1.88 Å) and one longer (2.51 Å) Ti(1)-Pt(1) bond length. There are two inequivalent W sites. In the first W site, W(1) is bonded in a 3-coordinate geometry to two equivalent Ti(1) and one W(2) atom. The W(1)-W(2) bond length is 1.62 Å. In the second W site, W(2) is bonded in a 3-coordinate geometry to one Ti(1), one W(1), and one Pt(1) atom. The W(2)-Pt(1) bond length is 1.39 Å. Pt(1) is bonded in a 3-coordinate geometry to two equivalent Ti(1) and one W(2) atom.
