Bis(2,6-diamino-3,5-dibromo-pyridinium) hexa-bromidostannate(IV).

ABSTRACT: The asymmetric unit of the title compound, (C(5)H(6)Br(2)N(3))(2)[SnBr(6)], contains one cation and one half-anion in which the Sn atom is located on a crystallographic centre of inversion and is in a quasi-octa-hedral geometry. The crystal structure is assembled via hydrogen-bonding inter-actions of two kinds, N(pyridine/amine)-H?Br-Sn, along with C-Br?Br-Sn interactions [3.4925?(19)?Å]. The cations are involved in ?-? stacking, which adds an extra supra-molecularity as it presents a strong case of offset-face-to-face motifs [centroid-centroid distance = 3.577?(3)?Å]. The inter-molecular hydrogen bonds, short Br?Br inter-actions and ?-? stacking result in the formation of a three-dimensional supra-molecular architecture.

Project description:The asymmetric unit of the title compound, 2C(5)H(8)N(3) (+)·2C(2)HO(4) (-)·H(2)O, contains two crystallographically independent 2,6-diamino-pyridinium cations, a pair of hydrogen oxalate anions and a water mol-ecule. Both 2,6-diamino-pyridinium cations are planar, with maximum deviations of 0.011?(2) and 0.015?(1)?Å, and are protonated at the pyridine N atoms.

Project description:In the title hydrated mol-ecular salt, (C(5)H(8)N(3))(2)[Zn(C(7)H(3)NO(4))(2)]·H(2)O, the Zn(II) atom is coordinated by two O,N,O'-tridentate pyridine-2,6-dicarboxyl-ate dianions, generating a slightly distorted trans-ZnN(2)O(4) octa-hedral coordination geometry for the metal ion. In the crystal, a network of O-H?O, N-H?O and C-H?O hydrogen bonds involving the cations, anions and water mol-ecules results in a three-dimensional network.

Bis(2,6-diamino-pyridinium) hydrogen phthalate nitrate monohydrate.

Project description:The title hydrated salt, 2C(5)H(8)N(3) (+)·C(8)H(5)O(4) (-)·NO(3) (-)·H(2)O, was obtained fortuitously from the reaction between 2,6-diamino-pyridine, phthalic acid and Co(NO(3))(2)·6H(2)O at 343?K. The asymmetric unit consists of two crystallographically independent 2,6-diamino-pyridinium cations, a hydrogen phthalate anion, a nitrate ion and a water mol-ecule of crystallization which in the crystal structure are linked by inter-molecular O-H?O and N-H?O hydrogen bonds into a three-dimensional network. In the hydrogen phthalate anion, there is a very strong intra-molecular O-H?O hydrogen bond.

Project description:In the title compound, 4C(5)H(8)N(3) (+)·2C(8)H(4)O(4) (2-)·C(5)H(7)N(3), the asymmetric unit consists of two protonated diamino-pyridine cations, one phthalate anion and one half of a diamino-pyridine mol-ecule, which has twofold rotation symmetry and is disordered over two positions with a site-occupancy ratio of 0.534?(3):0.466?(3). In the disordered structure, both pyridine rings are essentially planar, with maximum deviations of 0.011?(2) and 0.006?(2)?Å, and these two rings are inclined to one another at a dihedral angle of 79.86?(10)°. In the crystal structure, inter-molecular N-H?O and C-H?O hydrogen bonds link the ions and mol-ecules into a three-dimensional network. The structure is further stabilized by C-H?? inter-actions.

Bis(2,6-diamino-pyridinium) tartrate monohydrate.

Project description:In the title compound, 2C(5)H(8)N(3) (+)·C(4)H(4)O(6) (2-)·H(2)O, the two cations are essentially planar [maximum deviations = 0.023?(1) and 0.026?(1)?Å]. In one of the cations, the protonated N atom and one of the amino group H atoms are hydrogen bonded to one of the carboxyl groups of the dianion through a pair of N-H?O hydrogen bonds, forming an R(2) (2)(8) ring motif. In the crystal structure, the tartrate anions and water mol-ecules are linked into chains along the c axis by inter-molecular O-H?O and C-H?O hydrogen bonds. The cations further link the anions and water mol-ecules into a three-dimensional extended structure by a network of N-H?O hydrogen bonds. The crystal structure is also stabilized by weak inter-molecular ?-? inter-actions [centroid-centroid distance = 3.6950?(6)?Å].

1,5-Diamino-2,6-dibromo-9,10-anthraquinone.

Project description:In the title compound, C(14)H(8)Br(2)N(2)O(2), the mol-ecular structure features intra-molecular N-H?O [2.639?(2)?Å and 130°] and N-H?Br [3.053?(2)?Å and 114°] hydrogen bonding. Due to inversion symmetry, the asymmetric part of the unit cell consits of one half-mol-ecule. In the crystal, inversion dimers linked by pairs of N-H?O [2.955?(2)?Å and 135°] hydrogen bonds occur. The structure also features C=O?? [3.228?(2)?Å] and Br?Br [3.569?(1)?Å] contacts.

2,6-Diamino-pyridinium dihydrogen phosphate.

Project description:In the crystal structure of the title compound, C(5)H(8)N(3) (+)·H(2)PO(4) (-), N-H?O hydrogen bonds, involving the unprotonated amino-group and the NH(+) group in the pyridinium ring and dihydrogenphosphate O atoms, link the cations and anions. A long chain-like stacking of dihydrogenphosphate anions along the c-axis direction is constructed by O-H?O hydrogen bonds. Also along the c-axis direction, ?-? stacking between inversion-related pyridinium rings [centroid-centroid distance = 3.8051?(10)?Å] forms columnar stacks of cations.
