Thiocarbonate describes a family of anions with the general chemical formula CS3-xOx2- (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 1.33. The state of protonati...
