La Bi Bi
LaBi2 crystallizes in the triclinic P1 space group. La(1) is bonded in a distorted bent 150 degrees geometry to two equivalent Bi(2) and four equivalent Bi(1) atoms. There is one shorter (1.99 Å) and one longer (2.15 Å) La(1)-Bi(2) bond length. There are a spread of La(1)-Bi(1) bond distances ranging from 2.90-3.95 Å. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a 7-coordinate geometry to four equivalent La(1) and three equivalent Bi(2) atoms. There are a spread of Bi(1)-Bi(2) bond distances ranging from 2.57-3.59 Å. In the second Bi site, Bi(2) is bonded in a bent 150 degrees geometry to two equivalent La(1) and three equivalent Bi(1) atoms.
