Materials Data on H4Ru3C9N2O9 by Materials Project
Ru2NH2RuNH2(CO)9 crystallizes in the triclinic P-1 space group. The structure is zero-dimensional and consists of four azanide;ruthenium(1+) molecules, thirty-six formaldehyde molecules, and four Ru2NH2 clusters. In each Ru2NH2 cluster, there are two inequivalent Ru+2.67+ sites. In the first Ru+2.67+ site, Ru+2.67+ is bonded in a distorted L-shaped geometry to one N3- and one H1+ atom. The Ru–N bond length is 2.13 Å. The Ru–H bond length is 1.82 Å. In the second Ru+2.67+ site, Ru+2.67+ is bonded in a distorted L-shaped geometry to one N3- and one H1+ atom. The Ru–N bond length is 2.13 Å. The Ru–H bond length is 1.84 Å. N3- is bonded in a distorted single-bond geometry to two Ru+2.67+ and one H1+ atom. The N–H bond length is 1.02 Å. There are two inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a water-like geometry to two Ru+2.67+ atoms. In the second H1+ site, H1+ is bonded in a single-bond geometry to one N3- atom.
