Methyl (E)-3-(2-bromo-4,5-dimethoxybenzylidene)dithiocarbazate

چکیده
The title compound, C(11)H(13)BrN(2)O(2)S(2), was obtained from the condensation reaction of methyl dithio-carbazate and 2-bromo-4,5-dimeth-oxy-benzaldehyde. In the mol-ecule, the benzene ring and dithio-carbazate fragment are located on opposite sides of the C=N bond, showing an E conformation. The dithio-carbazate fragment is approximately planar (r.m.s deviation = 0.0281 Å) and the mean plane is oriented at a dihedral angle of 11.38 (15)° with respect to the benzene ring. In the crystal, pairs of N-H⋯S hydrogen bonds link the mol-ecules into centrosymmetric dimers.

The title compound, C(7)H(6)BrN(3)O, was obtained from the reaction of 6-bromo-1H-imidazo[4,5-b]pyridin-2(3H)-one with methyl iodide. All non-H atoms lie in a common plane [r.m.s deviation = 0.017 (1) Å]. The amino group is a hydrogen-bond donor to the carbonyl group of an inversion-related mol-ecule, the pair of hydrogen bonds giving rise to a hydrogen-bonded dimer.
