La La Ti Pt
La2TiPt crystallizes in the monoclinic Cm space group. There are two inequivalent La sites. In the first La site, La(1) is bonded in a 6-coordinate geometry to one La(2), four equivalent La(1), and one Ti(1) atom. The La(1)-La(2) bond length is 2.92 Å. All La(1)-La(1) bond lengths are 3.40 Å. The La(1)-Ti(1) bond length is 3.76 Å. In the second La site, La(2) is bonded in a distorted single-bond geometry to one La(1) and one Pt(1) atom. The La(2)-Pt(1) bond length is 2.22 Å. Ti(1) is bonded in a distorted single-bond geometry to one La(1) and one Pt(1) atom. The Ti(1)-Pt(1) bond length is 1.91 Å. Pt(1) is bonded in a distorted L-shaped geometry to one La(2) and one Ti(1) atom.
