Rb Pd Pd
RbPd2 crystallizes in the monoclinic Cm space group. The structure is zero-dimensional and consists of two RbPd2 clusters. Rb(1) is bonded in a linear geometry to one Pd(1) and one Pd(2) atom. The Rb(1)-Pd(1) bond length is 1.97 Å. The Rb(1)-Pd(2) bond length is 2.04 Å. There are two inequivalent Pd sites. In the first Pd site, Pd(1) is bonded in a single-bond geometry to one Rb(1) atom. In the second Pd site, Pd(2) is bonded in a single-bond geometry to one Rb(1) atom.
