Pt2Te2Cl crystallizes in the monoclinic Cm space group. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a single-bond geometry to one Pt(2), two equivalent Te(1), and one Cl(1) atom. The Pt(1)-Pt(2) bond length is 1.93 Å. Both Pt(1)-Te(1) bond lengths are 2.23 Å. The Pt(1)-Cl(1) bond length is 0.38 Å. In the second Pt site, Pt(2) is bonded in a 5-coordinate geometry to one Pt(1) and four equivalent Te(1) atoms. There are two shorter (2.89 Å) and two longer (3.01 Å) Pt(2)-Te(1) bond lengths. Te(1) is bonded in a 4-coordinate geometry to one Pt(1), two equivalent Pt(2), and two equivalent Cl(1) atoms. There is one shorter (2.24 Å) and one longer (2.93 Å) Te(1)-Cl(1) bond length. Cl(1) is bonded in a single-bond geometry to one Pt(1) and four equivalent Te(1) atoms.
