The structure described by La3ScBi5 crystallizes in the hexagonal P6_3/mcm space group. La(1) is bonded in a 9-coordinate geometry to four equivalent Bi(2) and five equivalent Bi(1) atoms. Sc(1) is bonded to six equivalent Bi(1) atoms to form face-sharing ScBi6 octahedra. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded to five equivalent La(1) and two equivalent Sc(1) atoms to form a mixture of distorted corner, face, and edge-sharing BiLa5Sc2 pentagonal bipyramids. In the second Bi site, Bi(2) is bonded in a 8-coordinate geometry to six equivalent La(1) and two equivalent Bi(2) atoms. is represented by the Crystallographic Information File (CIF) [CIF]
