Ethyl 2-amino-4-tert-butyl-1,3-thiazole-5-carboxylate and 6-methylimidazo[2,1-b]thiazole-2-amino-1,3-thiazole (1/1).
The structure of ethyl 2-amino-4-tert-butyl-1,3-thiazole-5carboxylate, C10H16N2O2S, (I), and the structure of the 1:1 adduct 6-methylimidazo[2,1-b]thiazole±2-amino-1,3-thiazole (1/1), C6H6N2S C3H4N2S, (II), have been determined. The molecules in (I) associate via a hydrogen-bonded R2(8) dimer consisting of NÐH N interactions, with the hydrogenbonding array additionally involving NÐH O interacti...
متن کامل2-Acetamido-4-p-tolyl-1,3-thiazole and 2-amino-4-p-tolyl-1,3-thiazolium chloride dihydrate.
The structures of 2-acetamido-4-tolyl-1,3-thiazole, C(12)H(12)N(2)OS, (I), and 2-amino-4-tolyl-1,3-thiazolium chloride dihydrate, C(10)H(11)N(2)S(+).Cl(-).2H(2)O, (II), reveal that both molecules are essentially planar, with the respective dihedral angles between the benzene and thiazole rings being 2.9 (1) and 10.39 (7) degrees . Compound (I) associates via a single N-H...O interaction to form...
متن کاملS-2-Amino-5-(dimethylammonio)phenyl sulfothioate
The title compound, C(8)H(12)N(2)O(3)S(2), has been isolated as an inter-mediate in the synthesis of methyl-ene blue dye, the best known phenothia-zine dye, and structurally characterized as a zwitterion. The crystal structure is dominated by inter-molecular N-H⋯O hydrogen bonds between the amine and sulfothio-ate groups, with graph-set motif C(9)R(2) (2)(8), involving anti-parallel chains and ...
متن کاملS-5-Amino-2-(dimethylammonio)phenyl sulfothioate
The title compound, C(8)H(12)N(2)O(3)S(2), has been isolated as a by-product in the synthesis of methyl-ene blue dye. The compound crystallizes with four independent mol-ecules in the unit cell (Z'= 4). The zwitterionic form of the mol-ecule was established on the basis of the hydrogen atom located at the dimethyl-amino group. The crystal structure is dominated by inter-molecular hydrogen bonds...
متن کامل2-{[4-(Dimethylamino)benzylidene]amino}phenyl disulfide
In the title mol-ecule, C(30)H(30)N(4)S(2), the two benzene rings connected through the disulfide chain form a dihedral angle of 88.7 (1)°, and the two benzene rings in the benzyl-ideneaniline fragments form dihedral angles of 34.0 (1) and 35.4 (1)°. The crystal packing exhibits no significantly short inter-molecular contacts.
