Bi B B Cl
B2BiCl is Cyanogen Chloride-like structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two B2BiCl clusters. There are two inequivalent B sites. In the first B site, B(1) is bonded in a linear geometry to one Bi(1) and one Cl(1) atom. The B(1)-Bi(1) bond length is 0.96 Å. The B(1)-Cl(1) bond length is 1.65 Å. In the second B site, B(2) is bonded in a single-bond geometry to one Cl(1) atom. The B(2)-Cl(1) bond length is 0.55 Å. Bi(1) is bonded in a single-bond geometry to one B(1) atom. Cl(1) is bonded in a linear geometry to one B(1) and one B(2) atom.
