AgCuBi2 is Copper structured and crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two AgCuBi2 clusters. Ag(1) is bonded in a single-bond geometry to one Cu(1) atom. The Ag(1)-Cu(1) bond length is 0.53 Å. Cu(1) is bonded in a distorted single-bond geometry to one Ag(1) and two equivalent Bi(1) atoms. Both Cu(1)-Bi(1) bond lengths are 1.91 Å. Bi(1) is bonded in a distorted single-bond geometry to one Cu(1) atom.
