La La La
La crystallizes in the triclinic P1 space group. There are three inequivalent La sites. In the first La site, La(1) is bonded in a 9-coordinate geometry to one La(3), two equivalent La(2), and six equivalent La(1) atoms. The La(1)-La(3) bond length is 3.50 Å. There is one shorter (3.75 Å) and one longer (4.06 Å) La(1)-La(2) bond length. All La(1)-La(1) bond lengths are 3.56 Å. In the second La site, La(2) is bonded in a distorted single-bond geometry to one La(3) and two equivalent La(1) atoms. The La(2)-La(3) bond length is 1.50 Å. In the third La site, La(3) is bonded in a distorted single-bond geometry to one La(1) and one La(2) atom.
