ScCoBi3 crystallizes in the trigonal R3m space group. Sc(1) is bonded in a 9-coordinate geometry to nine equivalent Bi(1) atoms. There are three shorter (3.09 Å) and six longer (3.68 Å) Sc(1)-Bi(1) bond lengths. Co(1) is bonded to six equivalent Bi(1) atoms to form corner-sharing CoBi6 octahedra. The corner-sharing octahedra are not tilted. There are three shorter (2.19 Å) and three longer (2.96 Å) Co(1)-Bi(1) bond lengths. Bi(1) is bonded in a 1-coordinate geometry to three equivalent Sc(1) and two equivalent Co(1) atoms.
