Graphical Abstract
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).

- 6aGeometry optimizations of the Ir tetramers were carried out by density functional theory (DFT) methods with the empirically parameterized hybrid functional B3LYP as implemented in Gaussian 03. The equilibrium structures have been characterized by a lack of imaginary vibrations. The 6-31g(d) basis set was applied to all elements except Ir which is described with the LANL2DZ basis set;
- 6bNMR spectroscopic calculations were carried out using the ADF 2007.01 program suite: ADF2007.01, SCM, Theoretical Chemistry, Vrije Universiteit, Amsterdam, The Netherlands, http://www.scm.com. Further details are given in the Supporting Information.
