Cr Bi
CrBi is alpha Po structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CrBi clusters. Cr(1) is bonded in a distorted single-bond geometry to one Bi(1) atom. The Cr(1)-Bi(1) bond length is 1.37 Å. Bi(1) is bonded in a distorted single-bond geometry to one Cr(1) atom.
