2-Chloro-5-nitropyridin-4-amine

2-Chloro-5-nitro­pyridin-4-amine

The title mol-ecule, C(5)H(4)ClN(3)O(2), possesses mirror symmetry, with all of the atoms lying in the mirror plane. There is an intra-molecular N-H⋯O hydrogen bond involving the adjacent -NO(2) and -NH(2) groups. A short C-H⋯O inter-action is also observed. In the crystal, adjacent mol-ecules are linked via N-H⋯Cl and N-H⋯N hydrogen bonds, forming chains propagating along [100].

3-Chloro-5-(trifluoro­meth­yl)pyridin-2-amine

In the title compound, C(6)H(4)ClF(3)N(2), an inter-mediate in the synthesis of the fungicide fluazinam, the F atoms of the trifluoro-methyl group are disordered over two sites in a 0.683 (14):0.317 (14) ratio. In the crystal structure, centrosymmetric dimers arise from pairs of N-H⋯N hydrogen bonds.

4-Chloro-6-meth­oxy­pyrimidin-2-amine

The title compound, C5H6ClN3O, is essentially planar with a maximum deviation of 0.0256 (11) Å for all non-H atoms. In the crystal, adjacent mol-ecules are linked by a pair of N-H⋯N hydrogen bonds, forming an inversion dimer with an R2(2)(8) ring motif. The dimers are further linked via N-H⋯O hydrogen bonds into an undulating sheet structure parallel to the bc plane.

2-Chloro-6-methyl­pyrimidin-4-amine

In the crystal structure of the title compound, C5H6ClN3, mol-ecules are linked by pairs of N-H⋯N hydrogen bonds, forming inversion dimers. These dimers are linked via N-H⋯N hydrogen bonds, forming a two-dimensional network lying parallel to (100). Inversion-related mol-ecules are also linked via a slipped π-π inter-action, with a centroid-centroid distance of 3.5259 (11) Å, a normal separation...
