LaSc3Br crystallizes in the trigonal R3m space group. La(1) is bonded in a 12-coordinate geometry to twelve equivalent Sc(1) atoms. There are a spread of La(1)-Sc(1) bond distances ranging from 3.04-4.27 Å. Sc(1) is bonded in a distorted single-bond geometry to four equivalent La(1) and two equivalent Br(1) atoms. There is one shorter (2.15 Å) and one longer (3.02 Å) Sc(1)-Br(1) bond length. Br(1) is bonded to six equivalent Sc(1) atoms to form distorted corner-sharing BrSc6 octahedra. The corner-sharing octahedra are not tilted.
