Tricarbonylchloroglycinatoruthenium(II) is an organoruthenium complex with the formula RuCl(H<sub>2</sub>NCH<sub>2</sub>CO<sub>2</sub>)(CO)<sub>3</sub>. A yellow solid, it is an amino acid complex consisting of an octahedral complex with three carbonyls, chloride, and bidentate glycinate ligands. The CO ligands are arranged in a facial geometry. The complex is prepared by treating dichlororuthenium tricarbonyl dimer with sodium glycinate. The complex has attracted attention as a CO-releasing molecule ("CORM").
