Materials Data on H26Os2N12Cl4O9 by Materials Project
(OsH12(N3O2)2)2H2O(Cl2)2 crystallizes in the monoclinic C2/c space group. The structure is zero-dimensional and consists of sixteen hydrochloric acid molecules, four water molecules, and eight OsH12(N3O2)2 clusters. In each OsH12(N3O2)2 cluster, Os8+ is bonded in an octahedral geometry to five N+1.67- and one O2- atom. There are a spread of Os–N bond distances ranging from 1.74–2.16 Å. The Os–O bond length is 2.05 Å. There are six inequivalent N+1.67- sites. In the first N+1.67- site, N+1.67- is bonded in a distorted trigonal non-coplanar geometry to one Os8+ and three H1+ atoms. There is one shorter (1.02 Å) and two longer (1.04 Å) N–H bond length. In the second N+1.67- site, N+1.67- is bonded in a trigonal planar geometry to three O2- atoms. There is two shorter (1.23 Å) and one longer (1.37 Å) N–O bond length. In the third N+1.67- site, N+1.67- is bonded in a linear geometry to one Os8+ and one O2- atom. The N–O bond length is 1.18 Å. In the fourth N+1.67- site, N+1.67- is bonded in a distorted trigonal non-coplanar geometry to one Os8+ and three H1+ atoms. All N–H bond lengths are 1.03 Å. In the fifth N+1.67- site, N+1.67- is bonded in a trigonal non-coplanar geometry to one Os8+ and three H1+ atoms. All N–H bond lengths are 1.03 Å. In the sixth N+1.67- site, N+1.67- is bonded in a trigonal non-coplanar geometry to one Os8+ and three H1+ atoms. There is two shorter (1.03 Å) and one longer (1.04 Å) N–H bond length. There are twelve inequivalent H1+ sites. In the first H1+ site, H1+ is bonded in a single-bond geometry to one N+1.67- atom. In the second H1+ site, H1+ is bonded in a single-bond geometry to one N+1.67- atom. In the third H1+ site, H1+ is bonded in a single-bond geometry to one N+1.67- atom. In the fourth H1+ site, H1+ is bonded in a single-bond geometry to one N+1.67- atom. In the fifth H1+ site, H1+ is bonded in a single-bond geometry to one N+1.67- atom. In the sixth H1+ site, H1+ is bonded in a single-bond geometry to one N+1.67- atom. In the seventh H1+ site, H1+ is bonded in a single-bond geometry to one N+1.67- atom. In the eighth H1+ site, H1+ is bonded in a single-bond geometry to one N+1.67- atom. In the ninth H1+ site, H1+ is bonded in a single-bond geometry to one N+1.67- atom. In the tenth H1+ site, H1+ is bonded in a single-bond geometry to one N+1.67- atom. In the eleventh H1+ site, H1+ is bonded in a single-bond geometry to one N+1.67- atom. In the twelfth H1+ site, H1+ is bonded in a single-bond geometry to one N+1.67- atom. There are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one N+1.67- atom. In the second O2- site, O2- is bonded in a bent 120 degrees geometry to one Os8+ and one N+1.67- atom. In the third O2- site, O2- is bonded in a single-bond geometry to one N+1.67- atom. In the fourth O2- site, O2- is bonded in a single-bond geometry to one N+1.67- atom.
