K Ga Bi Bi
KGaBi2 is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two KGaBi2 clusters. K(1) is bonded in a linear geometry to one Bi(1) and one Bi(2) atom. The K(1)-Bi(1) bond length is 0.52 Å. The K(1)-Bi(2) bond length is 1.28 Å. Ga(1) is bonded in a single-bond geometry to one Bi(2) atom. The Ga(1)-Bi(2) bond length is 1.62 Å. There are two inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a single-bond geometry to one K(1) atom. In the second Bi site, Bi(2) is bonded in a distorted linear geometry to one K(1) and one Ga(1) atom.
