3-Methyl­benzene-1,2-diamine

The title compound, C7H10N2, was synthesized from 2-methyl-6-nitro-aniline by a reduction reaction. In the crystal, molecules are linked via N-H⋯N hydrogen bonds, forming two-dimensional networks lying parallel to (100). These networks are stabilized by C-H⋯π and N-H⋯π inter-actions.

Pyridine-2,3-diamine

The mol-ecule of the title pyridine derivative, C(5)H(7)N(3), shows approximately non-crystallographic C(s) symmetry. Intra-cyclic angles cover the range 117.50 (14)-123.03 (15)°. In the crystal, N-H⋯N hydrogen bonds connect mol-ecules into a three-dimensional network. The closest inter-centroid distance between two π-systems occurs with the c-axis repeat at 3.9064 (12) Å.

3-Nitro­benzene-1,2-diamine

The mol-ecule of the title compound, C(6)H(7)N(3)O(2), a derivative of o-phenyl-enediamine, nearly shows non-crystallographic C(s) symmetry. C-C-C angles span the range 116.25 (11)-122.35 (11)°. In the crystal, inter-molecular N-H⋯O and N-H⋯N hydrogen bonds connect mol-ecules into undulating sheets perpendicular to the crystallographic a axis. A weak intra-molecular N-H⋯O hydrogen bond is also ...

Pyridine-2,5-diamine

In the title mol-ecule, C5H7N3, intra-cyclic angles cover the range 117.15 (10)-124.03 (11)°. The N atoms of the amino groups have trigonal-pyramidal configurations deviating slightly from the pyridine plane by 0.106 (2) and -0.042 (2) Å. In the crystal, the pyridine N atom serves as an acceptor of an N-H⋯N hydrogen bond which links two mol-ecules into a centrosymmetric dimer. Inter-molecular N...
