2-Amino-3-ammonio-pyridinium dichloride.

ABSTRACT: The asymmetric unit of the title compound, C(5)H(9)N(3) (2+)·2Cl(-), contains two diprotonated 2,3-diamino-pyridine cations and four chloride anions. In the crystal structure, the anions and cations are connected by inter-molecular N-H?Cl and C-H?Cl hydrogen bonds, forming a three-dimensional network. The crystal structure is further stabilized by ?-? inter-actions between pyridinium rings [centroid-centroid distance = 3.695?(1)?Å].

The asymmetric unit of the title compound, C(5)H(9)N(3) (2+)·2Cl(-), contains two diprotonated 2,3-diamino-pyridine cations and four chloride anions. In the crystal structure, the anions and cations are connected by inter-molecular N-H⋯Cl and C-H⋯Cl hydrogen bonds, forming a three-dimensional network. The crystal structure is further stabilized by π-π inter-actions between pyridinium rings [centroid-centroid distance = 3.695 (1) Å]. ...[more]

Redetermination of 3-(ammonio-meth-yl)pyridinium dichloride.

Project description:The crystal structure of the title compound, C(6)H(10)N(2) (2+)·2Cl(-), has been reported previously in the non-standard setting P2(1)/a [Genet (1965 ?). Bull. Soc. Fr. Miner. Crist.88, 463-470], with an R value of 0.16. The current redetermination improves significantly the precision of the geometric parameters. In the crystal packing, cations and anions are linked by inter-molecular N-H?Cl and C-H?Cl hydrogen bonds into a three-dimensional network.

4-Ammonio-benzamidinium dichloride.

Project description:The crystal structure of the title compound, C(7)H(11)N(3) (2+)·2Cl(-), has been determined as part of a project focusing on the ability of the benzamidine system to form strong hydrogen bonds in aqueous media. It is commonly used as a ligand in affinity chromatography for purification and immobilization of enzymes. A twofold rotation axis runs along the axis of the cation. The orientation of the amidinium group with respect to the benzene ring is indicated by the N-C-C-C torsion angle of 40.2 (1)°. In the crystal structure, cations and anions are linked via hydrogen bonds. The chloride anion is surrounded by four ammonium cations in a tetra-hedral environment. The aromatic rings of the amidinium cations are π-stacked, with a centroid-centroid distance of 4.178 (1) Å.

4-Amino-pyridinium 4-amino-benzene-sulfonate 4-ammonio-benzene-sulfonate monohydrate.

Project description:The asymmetric unit of the title compound, C(5)H(7)N(2) (+)·C(6)H(6)NO(3)S(-)·C(6)H(7)NO(3)S·H(2)O, contains one 4-ammonio-benzene-sulfonate zwitterion ((+)H(3)NC(6)H(4)SO(3) (-)), one 4-amino-benzene-sulfonate anion (H(2)NC(6)H(4)SO(3) (-)), one 4-amino-pyridinium cation and two half-mol-ecules of water, each lying on a twofold rotation axis. The various ions and molecules in the structure are linked through N-H⋯O, N-H⋯N and N-H⋯S hydrogen bonds and C-H-π inter-actions into a three-dimensional framework.

catena-Poly[bis-(4-amino-pyridinium) [[diaqua-manganese(II)]-di-?-chlorido] dichloride].

Project description:Single crystals of the title organic-inorganic hybrid, {(C(5)H(7)N(2))(2)[MnCl(2)(H(2)O)(2)]Cl(2)}(n), were synthesized from an ethanol solution containing manganese(II) chloride tetra-hydrate and 4-amino-pyridine under acidic conditions. The asymmetric unit contains a disordered organic cation (occupancies in the ratio 0.72:0.28), a chloride anion and an MnCl(H(2)O) moiety with the Mn(II) atom located on an inversion center. The structure is built up of infinite chains of edge-sharing [MnCl(4)(H(2)O)(2)] octa-hedra developing parallel to the a axis which are separated by the 4-amino-pyridinium ions and discrete chloride ions. The organic cations occupy the empty space around each inorganic chain. Structural cohesion is organized through N-H?Cl and O-H?Cl hydrogen bonds, which build up a three-dimensional network.

3-(Ammonio-meth-yl)pyridinium dibromide.

Project description:In the title salt, C(6)H(10)N(2) (2+)·2Br(-), the non-H atoms of the 3-methyl-pyridinium unit of the cation are almost coplanar (r.m.s. deviation = 0.0052?Å). In the crystal, the dications and Br anions are linked by a combination of six hydrogen bonds, viz. one N(py)-H?Br, two C-H?Br and three H(2)N-H?Br, into supra-molecular layers, parallel to the bc plane, composed of alternating R(2) (4)(10) and R(2) (4)(8) loops. Weak ?-? inter-actions between cationic rings with centroid-centroid distances of 3.891?(2)?Å are also observed.

3-(Ammonio-methyl)-pyridinium bis-(perchlorate).

Project description:In the title molecular salt, C6H10N2 (2+)·2ClO4 (-), the Cl-O bond lengths [anion 1: 1.369 (3)-1.415 (3); anion 2: 1.420 (2)-1.441 (2) Å] and the O-Cl-O angles [anion 1: 105.4 (2)-111.8 (4); anion 2: 107.8 (1)-110.3 (1)°] indicate a slight distortion of the perchlorate anions from regular tetra-hedral symmetry. In the crystal, the components are linked into columns along the a-axis direction via N-H⋯O and C-H⋯O hydrogen bonds, with stacks of the organic mol-ecules being surrounded by stacks of perchlorate anions.
