V Bi Bi Bi N
VBi3N is (Cubic) Perovskite structured and crystallizes in the trigonal R3m space group. V(1) is bonded in a 9-coordinate geometry to nine equivalent Bi(1) atoms. There are three shorter (2.98 Å) and six longer (3.47 Å) V(1)-Bi(1) bond lengths. Bi(1) is bonded in a 1-coordinate geometry to three equivalent V(1) and two equivalent N(1) atoms. There is one shorter (2.10 Å) and one longer (2.76 Å) Bi(1)-N(1) bond length. N(1) is bonded to six equivalent Bi(1) atoms to form corner-sharing NBi6 octahedra. The corner-sharing octahedra are not tilted.
