K V V Bi
KV2Bi crystallizes in the triclinic P1 space group. K(1) is bonded in a distorted single-bond geometry to one V(2), two equivalent V(1), and one Bi(1) atom. The K(1)-V(2) bond length is 1.10 Å. There is one shorter (3.05 Å) and one longer (3.82 Å) K(1)-V(1) bond length. The K(1)-Bi(1) bond length is 2.10 Å. There are two inequivalent V sites. In the first V site, V(1) is bonded in a 7-coordinate geometry to two equivalent K(1), one V(2), two equivalent V(1), and two equivalent Bi(1) atoms. The V(1)-V(2) bond length is 2.95 Å. Both V(1)-V(1) bond lengths are 3.17 Å. There is one shorter (2.99 Å) and one longer (3.38 Å) V(1)-Bi(1) bond length. In the second V site, V(2) is bonded in a single-bond geometry to one K(1) and one V(1) atom. Bi(1) is bonded in a distorted single-bond geometry to one K(1) and two equivalent V(1) atoms.
