Organic compounds structurally related to these anions are also called thiocarbonates. Like the carbonate dianion, the thiocarbonates are planar, with carbon at the center. The average bond order from C to S or O is 1.33. The state of protonation is usually not specified. These anions are good nucleophiles and good ligands Monothiocarbonate is the dianion CO2S2-, which has C2v symmetry. Monothiocarbonate arises by the hydrolysis of thiophosgene or the reaction of base with carbonyl sulfide:
