Thioformaldehyde, (H₂CS)₃

Thio-acids and Salts Derived from Carbon Disulphide

Carbon disulphide, like the dioxide, is the anhydride (or, more strictly, thioanhydride) of a feeble acid, thiocarbonic acid, H2CS3. Moreover, between carbonic and thiocarbonic acids a number of intermediate acids are capable of existence. They are as follows: Carbonic Acid. Thionearbonic Acid. Thiolcarbonic Acid. (Xanthic Acid). Thiolthioncarbonic Acid Dithiolcarbonic Acid. Thiocarbonic Acid.
