title: 4-Methyl-2-[N-(3,4-methylenedioxybenzylidene)hydrazino]thiazole and its reduction product, 4-methyl-2-[N-(3,4-methylenedioxybenzylidene)hydrazono]-4,5-dihydrothiazole.
abstract: The crystal structures of 4-methyl-2-[N-(3,4-methylenedioxybenzylidene)hydrazino]thiazole, C(12)H(11)N(3)O(2)S, and its reduction product 4-methyl-2-[N-(3,4-methylenedioxybenzylidene)hydrazono]-4,5-dihydrothiazole, C(12)H(13)N(3)O(2)S, have been determined and compared. In the reduction product, the tautomer observed bears an H atom on the exocyclic N atom. Both compounds form hydrogen-bonded dimers over centers of inversion.
