Three Ru-CO complexes, [Ru(Pbn)(2)(CO)(2)](2+), [Ru(pbn)(2)(CO)(COOH)(+), [Ru(pbn)(2)(CO)(COO)](0) [pbn = 2-(pyridin-2-yl)benzo[b]1,5-naphthyridine], exist as equilibrium mixtures in aqueous solutions. Thermal decarboxylation of [Ru(pbn)(2)(CO)(COOH)(+) and/or [Ru(pbn)(2)(CO)(COO)](0) induces a two -electron reduction of pbn to form [Ru(pbn)(pbnHH)(CO)(OH2)](2+) [pbnHH = 2-(pyridin-2-y1)-5,10-dihydrobenzo [b] -1,5-n aphthyridin e] in H2O.
