occurs to give a neutral, zwitter-ionic complex [Ru(bpy)2(8)]. The synthesis of the cationic complexes requires addition of a silver(I) salt (AgPF6 or AgBF4) to abstract Cl− from cis-[Ru(bpy)2Cl2] and 1H NMR spectroscopic data are consistent with interactions between Ag+ and the coordinated C^N ligand in [Ru(bpy)2(C^N)]+. The absorption spectra of [Ru(bpy)2(C^N)][PF6] (C^N = 1–6) are similar, but the

[Ir2(3)4Cl2]·2CH2Cl2 was determined. [Ir(6)2(bpy)][PF6] was prepared by nucleophilic substitution starting from [Ir(1)2(bpy)][PF6]. The [Ir(C^N)2(bpy)][PF6] complexes have been characterized by NMR, IR, absorption and emission spectroscopic and mass spectrometric methods. The single crystal structures of enantiomerically pure Δ-[Ir(1)2(bpy)][PF6] and of rac-4[Ir(1)2(bpy)][PF6]}·Et2O·2CH2Cl2 are described
