Abstract
In the title compound, [Rh(C<inf>2</inf>H<inf>11</inf>B<inf>9</inf>)(NO<inf>3</inf>)(C<inf>18</inf>H<inf>15</inf>P)<inf>2</inf>]·2.2CH<inf>2</inf>Cl<inf>2</inf>, studied as a 2.2-solvate of what was assumed to be dichloromethane, the nitrate ligand lies cis with respect to both cage C atoms. Accordingly, the compound displays a pronounced preferred exopolyhedral ligand orientation (ELO) which is traced to both the greater trans influence of the cage B over the cage C atoms and the greater trans influence of the triphenylphosphane ligands over the nitrate ligand. The overall molecular architecture therefore agrees with that of a number of similar 3-L-3,3-L′2-3,1,2-closo-MC<inf>2</inf>B<inf>9</inf>H<inf>11</inf> species in the literature.
