N-(3-Methyl-phen-yl)quinoxalin-2-amine monohydrate.

ABSTRACT: The quinoxaline system in the title hydrate, C(15)H(13)N(3)·H(2)O, is roughly planar, the r.m.s. deviation for the 18 non-H atoms being 0.188 Å; this conformation features a short intra-molecular C-H⋯N(pyrazine) inter-action. In the crystal, the amine H atom forms an N-H⋯O hydrogen bond to the water mol-ecule, which in turn forms two O-H⋯N hydrogen bonds to the pyrazine N atoms of different organic mol-ecules. These inter-actions lead to supra-molecular arrays in the bc plane that are two mol-ecules thick; additional π-π inter-actions stabilize the layers [ring centroid-centroid distance = 3.5923 (7) Å]. The layers stack along the a-axis direction via C-H⋯π contacts.

4-Methyl-N-(3-methyl-phen-yl)pyridin-2-amine.

Project description:The title amine, C(13)H(14)N(2), is twisted with a dihedral angle between the rings of 60.07?(9)°. The amine N-H group and pyridine N atom are syn allowing for the formation of centrosymmetric eight-membered {?HNCN}(2) synthons via N-H?N hydrogen bonds. The two-mol-ecule aggregates are sustained in the three-dimensional crystal packing via C-H?? and ?-? inter-actions [centroid-centroid distance for pyridyl rings = 3.7535?(12)?Å].

N-(3-Methyl-phen-yl)pyrimidin-2-amine.

Project description:Two independent mol-ecules comprise the asymmetric unit in the title compound, C(11)H(11)N(3). These differ in terms of the relative orientations of the aromatic rings: the first is somewhat twisted, while the second is approximately planar [dihedral angles between the pyrimidine and phenyl rings = 39.00 (8) and 4.59 (11)°]. The mol-ecules also form distinct patterns in their hydrogen bonding. The first independent mol-ecule forms centrosymmetric dimers featuring an eight-membered {HNCN}(2) synthon. The second independent mol-ecule forms an N-H⋯N hydrogen bond with the other pyrimidine N atom of the first mol-ecule. Thereby, tetra-meric aggregates are formed. These associate via C-H⋯N and C-H⋯π inter-actions, consolidating the crystal packing.
