چکیده
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 network exists in the crystal structure, with each H atom on the ammonium group exhibiting bifurcated inter-actions to the nitrate anion. Complex hydrogen-bonded ring and chain motifs are also evident, in particular a 26-membered ring with graph-set notation R(4) (4)(26) is observed.

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...

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 asymmetric unit of the title salt, [H3N(CH2)6NH3][(HO)O2P(CH2)6PO2(OH)], consists of one half of a hexane-1,6-diaminium dication and one half of a hexane-1,6-diyl bis-(hydrogen phospho-nate) dianion. Both are located around different centres of inversion (Wyckoff sites: 2a and 2d) of the space group P21/c. The shape of the hexane-1,6-diaminium cation is best described as a double hook. Both...

The title Schiff base ligand, C(20)H(20)Cl(2)N(2), was prepared by condensation of commercially available p-chloro-benzalde-hyde and (R,R)-1,2-diammonium-cyclo-hexane mono-(+)-tartrate. The cyclo-hexane ring adopts a chair conformation. The dihedral angle between the two aromatic rings is 62.52 (8)°. The crystal structure is stabilized by an inter-molecular C-H⋯Cl hydrogen bond.
