Ru2CuBi crystallizes in the monoclinic Pm space group. The structure is zero-dimensional and consists of one Ru2CuBi cluster. There are two inequivalent Ru sites. In the first Ru site, Ru(1) is bonded in a distorted single-bond geometry to one Cu(1) and one Bi(1) atom. The Ru(1)-Cu(1) bond length is 1.03 Å. The Ru(1)-Bi(1) bond length is 1.92 Å. In the second Ru site, Ru(2) is bonded in a distorted single-bond geometry to one Bi(1) atom. The Ru(2)-Bi(1) bond length is 1.68 Å. Cu(1) is bonded in a single-bond geometry to one Ru(1) atom. Bi(1) is bonded in a linear geometry to one Ru(1) and one Ru(2) atom.
