Abstract

(Pt)2RhN5Br5ClRhN5Br3Cl(Br)4 crystallizes in the monoclinic P2_1/m space group. The structure is zero-dimensional and consists of eight hydrobromic acid molecules, four platinum molecules, two RhN5Br3Cl clusters, and two RhN5Br5Cl clusters. In each RhN5Br3Cl cluster, Rh4+ is bonded in a distorted octahedral geometry to five N3- and one Cl1- atom. There are a spread of Rh–N bond distances ranging from 1.88–2.08 Å. The Rh–Cl bond length is 2.45 Å. There are three inequivalent N3- sites. In the first N3- site, N3- is bonded in a distorted L-shaped geometry to one Rh4+ and one Br1+ atom. The N–Br bond length is 1.81 Å. In the second N3- site, N3- is bonded in a distorted L-shaped geometry to one Rh4+ and one Br1+ atom. The N–Br bond length is 1.89 Å. In the third N3- site, N3- is bonded in a distorted bent 120 degrees geometry to one Rh4+ and one Br1+ atom. The N–Br bond length is 1.82 Å. There are three inequivalent Br1+ sites. In the first Br1+ site, Br1+ is bonded in an L-shaped geometry to two equivalent N3- atoms. In the second Br1+ site, Br1+ is bonded in a single-bond geometry to one N3- atom. In the third Br1+ site, Br1+ is bonded in an L-shaped geometry to two equivalent N3- atoms. Cl1- is bonded in a distorted single-bond geometry to one Rh4+ atom. In each RhN5Br5Cl cluster, Rh4+ is bonded in a distorted octahedral geometry to five N3- and one Cl1- atom. There are a spread of Rh–N bond distances ranging from 1.84–2.26 Å. The Rh–Cl bond length is 2.45 Å. There are four inequivalent N3- sites. In the first N3- site, N3- is bonded in a distorted trigonal non-coplanar geometry to one Rh4+ and two equivalent Br1+ atoms. Both N–Br bond lengths are 1.97 Å. In the second N3- site, N3- is bonded in a distorted trigonal non-coplanar geometry to one Rh4+ and two equivalent Br1+ atoms. Both N–Br bond lengths are 1.95 Å. In the third N3- site, N3- is bonded in a distorted single-bond geometry to one Rh4+ and one Br1+ atom. The N–Br bond length is 2.33 Å. In the fourth N3- site, N3- is bonded in a distorted single-bond geometry to one Rh4+ and one Br1+ atom. The N–Br bond length is 1.96 Å. There are three inequivalent Br1+ sites. In the first Br1+ site, Br1+ is bonded in a single-bond geometry to one N3- atom. In the second Br1+ site, Br1+ is bonded in a single-bond geometry to one N3- atom. In the third Br1+ site, Br1+ is bonded in a 1-coordinate geometry to two N3- atoms. Cl1- is bonded in a single-bond geometry to one Rh4+ atom.
