Cyclohexane-1,2-diammonium bis(pyridine-2-carboxylate)
In the dication of the title salt, C(6)H(16)N(2) (2+)·2C(6)H(4)NO(2) (-), the two ammonium groups are in the equatorial positions of the chair-shaped cyclo-hexyl ring. In the crystal, the cations and anions are linked by N-H⋯O and N-H⋯N hydrogen bonds, forming a layer network parallel to the ac plane. Weak π-π inter-actions between adjacent pyridine rings with a centroid-centroid distance of 3....

The asymmetric unit of the title compound, C6H5Cl2NO2S, contains two mol-ecules with similar conformations (r.m.s. overlay fit for the non-H atoms = 0.067 Å). Atoms attached to the pendent Csp (3)-S bond are arranged in a staggered conformation with one of the Cl atoms anti to the C atom in the aromatic ring [C-S-C-Cl torsion angles = 178.41 (11) and -176.70 (13)°]. In the crystal, mol-ecules a...
متن کاملHexane-1,6-diammonium bis(pyridine-2-carboxylate)
The title compound, C(6)H(18)N(2) (2+)·2C(6)H(4)NO(2) (-), consists of a doubly protonated hexa-methyl-enediammonium dication and two pyridine-2-carboxyl-ate anions. These ions inter-act by means of inter-molecular N-H⋯O and N-H⋯N hydrogen bonds to form a two-dimensional array. The carboxyl-ate groups of the anions appear to be delocalized on the basis of the C-O bond lengths.
متن کاملCrystal structure of 2-cyclohexyl-1,3-thiazolo[4,5-b]pyridine
In the title compound, C12H14N2S, the cyclo-hexane ring adopts a chair conformation with the exocyclic C-C bond in an equatorial orientation. The mean plane through the cyclo-hexane ring (all atoms) is twisted from the thia-zolo-pyridine ring system (r.m.s. deviation = 0.013 Å) by 39.57 (6)°. In the crystal, mol-ecules form (100) sheets, although there are no specific directional inter-actions ...
متن کاملCrystal structure of 4,6-diamino-2-(methylsulfanyl)pyridine-3-carbonitrile
The title pyrimidine derivative, C7H8N4S, is essentially planar, with a maximum deviation of 0.029 (2) Å from the mean plane of the non-H atoms. In the crystal, mol-ecules are linked by an inter-molecular bifurcated N-H⋯N hydrogen bond between the cyano N atom and the two amino groups, an N-H⋯N hydrogen bond between the two amino groups and a weak C-H⋯π inter-action, forming a three-dimensional...
