Thiocarbonic acid
Chemical compound
Thiocarbonic acid is an inorganic acid with the chemical formula H2CS3 (or S=C(SH)2). It is an analog of carbonic acid H2CO3 (or O=C(OH)2), in which all oxygen atoms are replaced with sulfur atoms. It is an unstable hydrophobic red oily liquid.[1]
It is often referred to as trithiocarbonic acid so as to differentiate it from other carbonic acids containing sulfur, such as monothiocarbonic O,O-acid S=C(OH)2, monothiocarbonic O,S-acid O=C(OH)(SH), dithiocarbonic O,S-acid S=C(OH)(SH) and dithiocarbonic S,S-acid O=C(SH)2 (see thiocarbonates).
