RhH2OCl5N2 crystallizes in the orthorhombic Pnma space group. The structure is zero-dimensional and consists of eight ammonia molecules and four pentachlororhodium;hydrate molecules.
RhN5H16(ClO4)2 is Cotunnite structured and crystallizes in the orthorhombic P2_12_12_1 space group. The structure is zero-dimensional and consists of eight ClO4 clusters and four RhN5H16 clusters. In each ClO4 cluster, there are four inequivalent O2- sites. In the first O2- site, O2- is bonded in a single-bond geometry to one Cl1- atom. The O–Cl bond length is 1.47 Å. In the second O2- site, O2- is bonded in a single-bond geometry to one Cl1- atom. The O–Cl bond length is 1.46 Å. In the third O2- site, O2- is bonded in a single-bond geometry to one Cl1- atom. The O–Cl bond length is 1.47 Å. In the fourth O2- site, O2- is bonded in a single-bond geometry to one Cl1- atom. The O–Cl bond length is 1.46 Å. Cl1- is bonded in a tetrahedral geometry to four O2- atoms. In each RhN5H16 cluster, Rh3+ is bonded in an octahedral geometry to five N+0.20- and one H1+ atom. There are a spread of Rh–N bond distances ranging from 2.10–2.27 Å. The Rh–H bond length is 1.56 Å. There are five inequivalent N+0.20- sites. In the first N+0.20- site, N+0.20- is bonded in a distorted trigonal non-coplanar geometry to one Rh3+ and three H1+ atoms. There is two shorter (1.02 Å) and one longer (1.03 Å) N–H bond length.
