6-Bromo-1,3-benzothiazol-2-amine
The r.m.s. deviation from the mean plane for the non-H atoms in the title compound, C(7)H(5)BrN(2)S, is 0.011 Å. In the crystal, the mol-ecules are linked by N-H⋯N and N-H⋯Br hydrogen bonds to generate (010) sheets. Weak aromatic π-π stacking [centroid-to-centroid separation = 3.884 (10) Å] and possible C-H⋯Br inter-actions are also observed. The crystal studied was found to be an inversion twin.

In the title mol-ecule, C(5)H(6)BrN(3), the pyrimidine ring is essentially planar, with an r.m.s. deviation of 0.007 Å. The Br and N atoms substituted to the pyrimidine ring are coplanar with the ring [displacements = 0.032 (1) and 0.009 (5) Å, respectively], while the methyl C atom lies 0.100 (15) Å from this plane with a dihedral angle between the pyrimidine ring and the methyl-amine group of...
متن کامل5-Bromo-2-chloropyrimidin-4-amine
In the title compound, C4H3BrClN3, the pyrimidine ring is essentially planar (r.m.s. deviation from the plane = 0.087 Å). In the crystal, pairs of N-H⋯N hydrogen bonds connect the mol-ecules into inversion dimers; these are connected by further N-H⋯N hydrogen bonds into a two-dimensional framework parallel to the bc plane.
متن کامل6-Methylpyridin-2-amine
In the title mol-ecule, C6H8N2, the endocyclic angles are in the range 118.43 (9)-122.65 (10)°. The mol-ecular skeleton is planar (r.m.s. deviation = 0.007 Å). One of the two amino H atoms is involved in an N-H⋯N hydrogen bond, forming an inversion dimer, while the other amino H atom participates in N-H⋯π inter-actions between the dimers, forming layers parallel to (100).
متن کامل5-(4-Bromo-2-nitrophenyl)-1,3,4-thiadiazol-2-amine
The title compound, C(8)H(5)BrN(4)O(2)S, was synthesized by the reaction of 4-bromo-2-nitro-benzoic acid with thio-semi-carbazide. The dihedral angle between the thia-diazole and benzene rings is 40.5 (2)°. In the crystal, the strongest N-H⋯N inter-molecular hydrogen bond, between the amine group and one thia-diazole N atom, forms centrosymmetric dimers. The other amine H atom extends the supra...
