V Ni Bi Bi
VNiBi2 crystallizes in the monoclinic Pm space group. V(1) is bonded in a distorted single-bond geometry to one Ni(1) and two equivalent Bi(1) atoms. The V(1)-Ni(1) bond length is 1.62 Å. Both V(1)-Bi(1) bond lengths are 2.66 Å. Ni(1) is bonded in a 3-coordinate geometry to one V(1) and four equivalent Bi(1) atoms. There are two shorter (2.04 Å) and two longer (2.89 Å) Ni(1)-Bi(1) bond lengths. Bi(1) is bonded in a 4-coordinate geometry to one V(1), two equivalent Ni(1), and one Bi(1) atom. The Bi(1)-Bi(1) bond length is 2.09 Å.
