4-Ethoxypyridin-2-amine
The title compound, C(7)H(10)N(2)O, crystallizes with two independent mol-ecules in the asymmetric unit. The bond lengths and angles in the mol-ecules are within normal ranges. The crystal structure is stabilized by inter-molecular N-H⋯N hydrogen bonds, linking the two independent mol-ecules into hydrogen-bonded dimers.
متن کامل2-Chloropyrimidin-4-amine
In the title pyrimidine derivative, C(4)H(4)ClN(3), the 2-chloro and 4-amino substituents almost lie in the mean plane of the pyrimidine ring, with deviations of 0.003 (1) Å for the Cl atom, and 0.020 (1) Å for the N atom. In the crystal, molecules are linked via pairs of N-H⋯N hydrogen bonds, forming inversion dimers. These dimers are further linked via N-H⋯N hydrogen bonds, forming an undulat...
متن کاملN-(4-Chlorophenyl)-4-methylpyridin-2-amine
In the title compound, C(12)H(11)ClN(2), the dihedral angle between the benzene and pyridyl rings is 48.03 (8)°. Twists are also evident in the mol-ecule, in particular about the N(a)-C(b) (a = amine and b = benzene) bond [C-N-C-C = -144.79 (18)°]. In the crystal, inversion dimers linked by pairs of N-H⋯N hydrogen bonds result in the formation of eight-membered {⋯NCNH}(2) synthons [or R(2) (2)(...
متن کامل2-(4-Fluorobenzylidene)-N-(4-methoxybenzylidene)-1,3,4-thiadiazol-2-amine
The title compound, C(16)H(12)FN(3)OS, was synthesized by the reaction of 5-(4-meth-oxy-phen-yl)-1,3,4-thia-diazol-2-amine and 4-fluoro-benzaldehyde. An intra-molecular C-H⋯S hydrogen bond results in the formation of two five-membered rings. In the crystal structure, inter-molecular C-H⋯N hydrogen bonding links the mol-ecules, forming a two-dimensional network.
متن کامل4-(4-Fluorophenyl)-6-(2-furyl)pyrimidin-2-amine
Mol-ecules of the title compound, C(14)H(10)FN(3)O, are essentially planar and in the crystal structure they form dimers via hydrogen bonds, involving pyrimidinyl N atoms and amino H atoms, about inversion centers. The centroids of the furyl and pyrimidinyl rings are separated by 3.489 (2)Å, indicating π-π stacking inter-actions.
