A phenyl…bpym…phenyl π interaction together with a trapping of BF 4 ⊖counterions by solvent molecules, form the basis for the intense solid‐state luminescence of 1 . This conclusion follows from the fact that with a series of other arylphosphane ligands, with PF 6 ⊖or ClO 4 ⊖as counterions, or even in solution, luminescence from the metal‐to‐ligand chargetransfer excited state is either very weak or totally absent.
