PtIn2Cl crystallizes in the trigonal R3m space group. Pt(1) is bonded in a 11-coordinate geometry to three equivalent In(2), four equivalent In(1), and four equivalent Cl(1) atoms. All Pt(1)-In(2) bond lengths are 3.27 Å. There is one shorter (2.81 Å) and three longer (3.16 Å) Pt(1)-In(1) bond lengths. There is one shorter (2.81 Å) and three longer (3.16 Å) Pt(1)-Cl(1) bond lengths. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 5-coordinate geometry to four equivalent Pt(1) and one In(2) atom. The In(1)-In(2) bond length is 2.81 Å. In the second In site, In(2) is bonded in a distorted trigonal planar geometry to three equivalent Pt(1), one In(1), and three equivalent Cl(1) atoms. All In(2)-Cl(1) bond lengths are 2.90 Å. Cl(1) is bonded to four equivalent Pt(1) and three equivalent In(2) atoms to form a mixture of corner and edge-sharing ClIn3Pt4 trigonal pyramids.
