La Mg Pt Pt
MgLaPt2 is alpha Niobium phosphide-derived structured and crystallizes in the triclinic P1 space group. The structure is zero-dimensional and consists of one MgLaPt2 cluster. Mg(1) is bonded in a 2-coordinate geometry to one La(1) and one Pt(2) atom. The Mg(1)-La(1) bond length is 0.73 Å. The Mg(1)-Pt(2) bond length is 1.19 Å. La(1) is bonded in a distorted L-shaped geometry to one Mg(1) and one Pt(2) atom. The La(1)-Pt(2) bond length is 1.09 Å. There are two inequivalent Pt sites. In the first Pt site, Pt(1) is bonded in a 1-coordinate geometry to one Pt(2) atom. The Pt(1)-Pt(2) bond length is 1.50 Å. In the second Pt site, Pt(2) is bonded in a 2-coordinate geometry to one Mg(1), one La(1), and one Pt(1) atom.
