CrAgBi is alpha Niobium phosphide-derived structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two CrAgBi clusters. Cr(1) is bonded in a single-bond geometry to one Ag(1) atom. The Cr(1)-Ag(1) bond length is 1.85 Å. Ag(1) is bonded in a distorted linear geometry to one Cr(1) and one Bi(1) atom. The Ag(1)-Bi(1) bond length is 0.34 Å. Bi(1) is bonded in a single-bond geometry to one Ag(1) atom.
