Tl In In Pt
PtTlIn2 crystallizes in the monoclinic Cm space group. Pt(1) is bonded in a 1-coordinate geometry to one Tl(1), one In(1), and one In(2) atom. The Pt(1)-Tl(1) bond length is 3.14 Å. The Pt(1)-In(1) bond length is 1.64 Å. The Pt(1)-In(2) bond length is 3.14 Å. Tl(1) is bonded in a 7-coordinate geometry to one Pt(1), four equivalent Tl(1), one In(1), and one In(2) atom. All Tl(1)-Tl(1) bond lengths are 3.31 Å. The Tl(1)-In(1) bond length is 3.31 Å. The Tl(1)-In(2) bond length is 3.31 Å. There are two inequivalent In sites. In the first In site, In(1) is bonded in a 1-coordinate geometry to one Pt(1), one Tl(1), and one In(2) atom. The In(1)-In(2) bond length is 2.95 Å. In the second In site, In(2) is bonded in a 7-coordinate geometry to one Pt(1), one Tl(1), one In(1), and four equivalent In(2) atoms. All In(2)-In(2) bond lengths are 3.31 Å.
