Ta2PtTe crystallizes in the triclinic P1 space group. There are two inequivalent Ta sites. In the first Ta site, Ta(1) is bonded in a 6-coordinate geometry to two equivalent Ta(2), two equivalent Pt(1), and two equivalent Te(1) atoms. There is one shorter (2.36 Å) and one longer (2.46 Å) Ta(1)-Ta(2) bond length. There is one shorter (2.40 Å) and one longer (2.72 Å) Ta(1)-Pt(1) bond length. There is one shorter (2.50 Å) and one longer (2.81 Å) Ta(1)-Te(1) bond length. In the second Ta site, Ta(2) is bonded in a 6-coordinate geometry to two equivalent Ta(1), two equivalent Pt(1), and two equivalent Te(1) atoms. There is one shorter (2.50 Å) and one longer (2.81 Å) Ta(2)-Pt(1) bond length. There is one shorter (2.40 Å) and one longer (2.72 Å) Ta(2)-Te(1) bond length. Pt(1) is bonded in a 5-coordinate geometry to two equivalent Ta(1), two equivalent Ta(2), and one Te(1) atom. The Pt(1)-Te(1) bond length is 1.44 Å. Te(1) is bonded in a 5-coordinate geometry to two equivalent Ta(1), two equivalent Ta(2), and one Pt(1) atom.
