1,3,5-Triazaadamantan-7-amine
The title compound, C(7)H(14)N(4), represents the first structurally characterized, isolated triaza-adamantane. In the crystal structure, weak inter-molecular N-H⋯N hydrogen bonds link the mol-ecules into columns about the crystallographic fourfold axis.
متن کاملBenzothiazol-2-amine–3-methoxycarbonyl-7-oxabicyclo[2.2.1]hept-5-ene-2-carboxylic acid (1/1)
In the title 1:1 adduct, C(7)H(6)N(2)S·C(9)H(10)O(5), all non-H atoms of the benzothia-zol-2-amine mol-ecule are essentially coplanar, with a maximum deviation of 0.0286 (9) Å for the S atom. In the crystal, inter-molecular N-H⋯O and O-H⋯N hydrogen bonds connect two mol-ecules of each type into centrosymmetric four-component clusters.
متن کامل3-Benzyloxypyridin-2-amine
In the title compound, C(12)H(12)N(2)O, the dihedral angle between the planes of the pyridine and phenyl rings plane is 35.94 (12)°. In the crystal structure, centrosymmetrically related mol-ecules are linked by a pair of N-H⋯N hydrogen bonds, forming a dimer with an R(2) (2)(8) ring motif. In addition, there is an intra-molecular N-H⋯O inter-action.
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 کامل4-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.
