La Bi Bi Sb
LaBi2Sb crystallizes in the monoclinic Cm space group. La(1) is bonded to eight equivalent Bi(1) and four equivalent Sb(1) atoms to form a mixture of face and corner-sharing LaBi8Sb4 cuboctahedra. There are a spread of La(1)-Bi(1) bond distances ranging from 3.25-3.81 Å. There are a spread of La(1)-Sb(1) bond distances ranging from 3.17-3.78 Å. Bi(1) is bonded in a 10-coordinate geometry to four equivalent La(1), three equivalent Bi(1), and three equivalent Sb(1) atoms. There is one shorter (3.17 Å) and two longer (3.49 Å) Bi(1)-Bi(1) bond lengths. There are a spread of Bi(1)-Sb(1) bond distances ranging from 3.25-3.56 Å. Sb(1) is bonded in a 10-coordinate geometry to four equivalent La(1) and six equivalent Bi(1) atoms.
