tautomers and deprotonated form of mercaptobenzothiazole the molecule is planar with a c=s double bond, so the name mercaptobenzothiazole is a misnomer, a more appropriate name could be benzothiazoline-2-thione.solution measurements by nmr spectroscopy could not measure the presence of the thiol tautomer that the name implies, instead it exists as a thione/dithiocarbamate and the hydrogen.
