empirical formula Ru(cht)Cl2 has been shown to be dimeric with the cycloheptatriene (cht) bonding as a tridentate ligand. This complex reacts with Group 5B Lewis bases (L) to give monomers [Ru(cht)Cl2L]. Reaction of the dimer with halide-abstracting thallium salts gives the complexes [Ru(cht)ClL2]+[L2=(MeCN)2 or 2,2′-bipyridyl(bipy)]. The complexes [Ru(cht)Cl2L][L = PPh3 or AsPh3] react with thallium β-diketonates
