Hexane-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.

The hexane-1,6-diammonium cation of the title compound, C(6)H(18)N(2) (2+)·2NO(3) (-), lies across a crystallographic inversion centre and shows significant deviation from planarity in the hydro-carbon chain. This is evident from the torsion angle of -64.0°(2) along the N-C-C-C bond and thse torsion angle of -67.1°(2) along the C-C-C-C bonds. An intricate three-dimensional hydrogen-bonding netw...

The asymmetric unit of the title compound, {(C(6)H(18)N(2))(0.5)[MnBr(2)(C(6)H(4)NO(2))(H(2)O)]}(n), contains the repeat unit of the complex anion and one-half of a hexane-1,6-diammonium cation that is located on a twofold rotation axis. In the anionic polymer, the Mn(2+) ions are bridged by the pyridine-carboxyl-ate (pic) anion ligand, forming a chain structure along the c axis. The Mn(2+) ion...
متن کامل3-Hydroxypyridinium-2-carboxylate
Comparable to many amino acids, the title compound, C(6)H(5)NO(3), is a substitution product of picolinic acid. The mol-ecule shows approximate non-crystallographic C(s) symmetry. Like many amino acids, the mol-ecule is present in its zwitterionic state. Intra- as well as inter-molecular hydrogen bonds are observed, the latter connecting the mol-ecules into zigzag chains along the crystallograp...
متن کاملCyclohexane-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....
