K Nb Bi
KNbBi crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two KNbBi clusters. K(1) is bonded in a distorted linear geometry to one Nb(1) and one Bi(1) atom. The K(1)-Nb(1) bond length is 2.22 Å. The K(1)-Bi(1) bond length is 1.68 Å. Nb(1) is bonded in a distorted single-bond geometry to one K(1) atom. Bi(1) is bonded in a single-bond geometry to one K(1) atom.
