Tl In Sn Pt
PtTlInSn crystallizes in the trigonal R3m space group. Pt(1) is bonded in a 2-coordinate geometry to one Tl(1), three equivalent In(1), and one Sn(1) atom. The Pt(1)-Tl(1) bond length is 2.50 Å. All Pt(1)-In(1) bond lengths are 3.06 Å. The Pt(1)-Sn(1) bond length is 2.50 Å. Tl(1) is bonded in a distorted single-bond geometry to one Pt(1) and three equivalent In(1) atoms. All Tl(1)-In(1) bond lengths are 3.05 Å. In(1) is bonded in a 10-coordinate geometry to three equivalent Pt(1), three equivalent Tl(1), and four equivalent Sn(1) atoms. There is one shorter (2.50 Å) and three longer (3.37 Å) In(1)-Sn(1) bond lengths. Sn(1) is bonded in a 2-coordinate geometry to one Pt(1) and four equivalent In(1) atoms.
