La Sb Sb Pt
LaPtSb2 crystallizes in the triclinic P1 space group. La(1) is bonded in a 2-coordinate geometry to one Pt(1), one Sb(1), and three equivalent Sb(2) atoms. The La(1)-Pt(1) bond length is 2.50 Å. The La(1)-Sb(1) bond length is 1.77 Å. There are a spread of La(1)-Sb(2) bond distances ranging from 3.10-3.98 Å. Pt(1) is bonded in a distorted single-bond geometry to one La(1) and two equivalent Sb(2) atoms. There is one shorter (2.92 Å) and one longer (3.06 Å) Pt(1)-Sb(2) bond length. There are two inequivalent Sb sites. In the first Sb site, Sb(1) is bonded in a distorted single-bond geometry to one La(1) and one Sb(2) atom. The Sb(1)-Sb(2) bond length is 1.83 Å. In the second Sb site, Sb(2) is bonded in a 6-coordinate geometry to three equivalent La(1), two equivalent Pt(1), and one Sb(1) atom.
