Bi Bi Bi Ru
RuBi3 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two RuBi3 clusters. Ru(1) is bonded in a distorted single-bond geometry to one Bi(2) atom. The Ru(1)-Bi(2) bond length is 2.39 Å. There are three inequivalent Bi sites. In the first Bi site, Bi(1) is bonded in a single-bond geometry to one Bi(2) and one Bi(3) atom. The Bi(1)-Bi(2) bond length is 1.60 Å. The Bi(1)-Bi(3) bond length is 0.21 Å. In the second Bi site, Bi(2) is bonded in a 2-coordinate geometry to one Ru(1) and one Bi(1) atom. In the third Bi site, Bi(3) is bonded in a single-bond geometry to one Bi(1) atom.
