Thiocarbonate
(重定向自Dithiocarbonate)
Thiocarbonate describes a family of anions with the general chemical formula CS
3−xO2−
x (x = 0, 1, or 2). 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 ⁄3. The state of protonation is usually not specified. These anions are good nucleophiles and good ligands.
