Materials Data on HRuRh(CO)6 by Materials Project
RhRu2RhH2(CO)12 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of twenty-four formaldehyde molecules, two rhodium molecules, and two Ru2RhH2 clusters. In each Ru2RhH2 cluster, there are two inequivalent Ru2+ sites. In the first Ru2+ site, Ru2+ is bonded in an L-shaped geometry to two H1+ atoms. There is one shorter (1.78 Å) and one longer (1.79 Å) Ru–H bond length. In the second Ru2+ site, Ru2+ is bonded in a distorted single-bond geometry to one H1+ atom. The Ru–H bond length is 1.83 Å. Rh3+ is bonded in a distorted single-bond geometry to one H1+ atom. The Rh–H bond length is 1.78 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a water-like geometry to one Ru2+ and one Rh3+ atom. In the second H1+ site, H1+ is bonded in a bent 120 degrees geometry to two Ru2+ atoms.
