A series of bimetallic complexes of ruthenium(II) bridged by heterocyclic ligands formed by the condensation of 4,5-diazafluoren-9-one with various diamines, hydrazine, 1,4-phenylenediamine, benzidine, and 4,4'-methylenedianiline, results in metal centers separated by various distances. The complexes give rise to metal-to-ligand charge-transfer
