In the title compound, [Rh(C 2 H 11 B 9 )(NO 3 )(C 18 H 15 P) 2 ]·2.2CH 2 Cl 2 , 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 ‐ M C 2 B 9 H 11 species in the literature.
