“…In confirmation of the above, the deuteration of bipyridine ligand and excited state lifetime observations of [Ru(bpy) 2 L](PF 4 ) 2 confirmed that the emitting state of the complex was located on the triazine ligand [31]. The kinetic liability of silver complexes, and especially their ability to undergo ligand scrambling reactions, is well-documented [32,33]; therefore, the complete absence of emission in the silver complex was not unexpected. The free rotation of the phenyl rings on the diimine backbone is the most probable reason for the low intensity emission in the copper compound.…”

The synthesis of a substituted diimine with a bipydirine-type backbone, (3-(2-pyridyl)-5,6-diphenyl-1,2,4-triazine, L) and its coordination towards Cu(I) and Ag(I) is studied in the presence of diphosphine ligand bis(diphenylphosphino)methane, dppm. The metal complexes are characterized by IR, 1H, and 13C NMR and single crystal X ray diffraction studies. They are dinuclear, as they are held by diphosphine bridges between the tetrahedral metal centers, forming eight-membered ring with the participation of the bridging diphosphinomethane ligands. Within each ring, the planar orientations of M2P2 and of all four P atoms are realized. Solid state excitation spectra are dominated by metal-to-ligand charge transfer bands (MLCT), while geometry relaxation permits only low-intensity emission for the copper compound.
