Butterfly clusters : Hydrogenation of a cationic iridium complex with the sterically bulky N‐ligand tetrahydroquinoline (thq) leads to the formation of two distinct tetrameric polyhydrides (see scheme; Ir green, N blue, P purple), which differ by exchanging one thq ligand for hydride. Both complexes have butterfly structures, with similar core geometries, but markedly different hinge angles (40.8° for 1 and 9.1° for 2 ).
