La Tl In Pt
LaPtTlIn crystallizes in the trigonal R3m space group. La(1) is bonded in a 5-coordinate geometry to one Pt(1), one Tl(1), and three equivalent In(1) atoms. The La(1)-Pt(1) bond length is 2.18 Å. The La(1)-Tl(1) bond length is 2.18 Å. All La(1)-In(1) bond lengths are 2.99 Å. Pt(1) is bonded to one La(1), three equivalent Tl(1), and one In(1) atom to form distorted PtLaTl3In trigonal bipyramids that share corners with six equivalent Pt(1)LaTl3In trigonal bipyramids,  a cornercorner with one Tl(1)LaPt3 trigonal pyramid, and corners with three equivalent In(1)La3Pt trigonal pyramids. All Pt(1)-Tl(1) bond lengths are 2.99 Å. The Pt(1)-In(1) bond length is 2.18 Å. Tl(1) is bonded to one La(1) and three equivalent Pt(1) atoms to form distorted TlLaPt3 trigonal pyramids that share  a cornercorner with one Pt(1)LaTl3In trigonal bipyramid, corners with six equivalent Tl(1)LaPt3 trigonal pyramids, and edges with three equivalent In(1)La3Pt trigonal pyramids. In(1) is bonded to three equivalent La(1) and one Pt(1) atom to form distorted InLa3Pt trigonal pyramids that share corners with three equivalent Pt(1)LaTl3In trigonal bipyramids, corners with six equivalent In(1)La3Pt trigonal pyramids, and edges with three equivalent Tl(1)LaPt3 trigonal pyramids.
