LaPtSb2 crystallizes in the trigonal R3m space group. La(1) is bonded in a distorted linear geometry to one Pt(1), one Sb(2), and three equivalent Sb(1) atoms. The La(1)-Pt(1) bond length is 1.90 Å. The La(1)-Sb(2) bond length is 1.90 Å. All La(1)-Sb(1) bond lengths are 3.06 Å. Pt(1) is bonded in a distorted linear geometry to one La(1) and one Sb(1) atom. The Pt(1)-Sb(1) bond length is 1.90 Å. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded to three equivalent La(1) and one Pt(1) atom to form distorted corner-sharing SbLa3Pt trigonal pyramids. In the second Sb site, Sb(2) is bonded in a single-bond geometry to one La(1) atom.
