Abstract: In the title compound, [RhCl₂(C₁₈H₃₂N₄)]PF₆, the Rh^III ion lies at the centre of a distorted octahedron of two axial chloride and four equatorial aza ligands. Within estimated error, the complex cation possesses non-crystallographic mirror symmetry. The Rh-Cl distances of 2.345  (3) and 2.349  (3)  Å are equivalent, as are the three Rh-Nsp³ distances [mean 2.145  (7)  Å]. The Rh-Nsp² distance is much shorter at 1.964  (7)  Å, reflecting the different hybridization of this donor atom. The four N atoms are not coplanar, and the metal ion lies out of the N₄ plane by 0.013  (3)  Å, suggesting that, with an ionic radius of 0.805  Å, the Rh^III ion is somewhat large for the macrocyclic cavity.
