The crystal structure of the IPrCl functionalized rhodium–dinuclear complex reveals an intermolecular Cl···Cl halogen bond. The chlorido-bridges can be cleaved by pyridine to afford the corresponding mononuclear derivatives RhCl(η2-coe)(NHC)(py). These complexes are efficient alkyne hydropyridonation catalysts, with the IMes complex exhibiting the highest reactivity within the series. © 2026 The Author(s).
