Ru(MC33)(CO)2(H2O) was obtained in yields of up to 97% using a pincer-type ligand containing the bis(carboxamide) moiety and ruthenium(0) carbonyl precursor. Ru(AC)(CO)2(H2O) having a pincer-type acyclic ligand AC was also synthesized in a similar manner to Ru(MC33)(CO)2(H2O). Mono(phosphine) and bis(phosphite) complexes were formed via the selective thermal ligand exchange of CO with phosphorus ligands
