2,6-Diamino-pyridinium tetra-phenyl-borate-1,2-bis-(5,7-dimethyl-1,8-naphthyridin-2-yl)diazene (1/1).

ABSTRACT: In the title compound, C(5)H(8)N(3) (+)·C(24)H(20)B(-)·C(20)H(18)N(6), the 1,2-bis-(5,7-dimethyl-1,8-naphthyridin-2-yl)diazene mol-ecule is essentially planar (r.m.s. deviation = 0.0045?Å) and aligned in nearly coplanar manner with the 2,6-diamino-pyridinium ion, making a dihedral angle of 5.19?(5)°. The diamino-pyridine mol-ecule is protonated on the central pyridine N atom and the B atom bears the counter-charge. The amine groups of the diamino pyridinium cation form intra-molecular N-H?N hydrogen bonds, resulting in linear and bent inter-actions with the naphthyridine ring system.

Project description:In the title compound, C(20)H(18)B(2)F(4)N(6), the bis-(5,7-dimethyl-1,8-naphthyridin-2-yl)diazene molecule is bis-ected by a symmetry centre midway between the central N atoms of the diazene group. Each of the symmetry-related halves of the molecule binds to a B atom through an N,N'-bite. Two terminal F ions complete the distorted BN(2)F(2) tetra-hedral geometry around each B atom. The BF(2) plane is almost perpendicular to the boron-naphthyridine ring plane, with a dihedral angle of 87.8?(2)°. The main inter-actions in the crystal structure are some C-H?F hydrogen bonds and ?-? contacts between 1,8-naphthyridine rings [centroid-centroid distance = 4.005?(1)?Å].

7-[4-(5,7-Dimethyl-1,8-naphthyridin-2-yl-oxy)phen-oxy]-2,4-dimethyl-1,8-naphthyridine methanol disolvate.

Project description:The title compound, C(26)H(22)N(4)O(2)·2CH(3)OH, was synthesized and characterized by (1)H NMR spectroscopy and X-ray structure analysis.

Tetra-kis(2,6-diamino-pyridinium) diphthalate 2,6-diamino-pyridine.

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.

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.

2,6-Diamino-pyridinium 2-carb-oxy-benzoate.

Project description:In the crystal of the title mol-ecular salt, C(5)H(8)N(3) (+)·C(8)H(5)O(4) (-), the diamino-pyridine cation and the phthalate anion are linked by a pair of N-H⋯O hydrogen bonds. Within the phthalate anion, an almost symmetrical O-H⋯O hydrogen bond is observed. The ion pairs are linked by further N-H⋯O hydrogen bonds, generating a two-dimensional network lying parallel to (10).

2,6-Dimethyl-pyridinium bromide.

Project description:The asymmetric unit of the title salt, C(7)H(10)N(+)·Br(-), comprises two 2,6-dimethyl-pyridinium cations and two bromide anions. One cation and one anion are situated in general positions, while the other cation and the other anion lie on a crystallographic mirror plane parallel to (010). Each pair of ions inter-act via N-H?Br and C-H?Br hydrogen bonding, generating motifs depending on the cation and anion involved. Thus, the cation and the anion on the mirror plane generate infinite chains along the c axis, while the other ionic pair leads to sheets parallel to the ac plane. In the overall crystal packing, both motifs alternate along the b axis, with a single layer of the chain motif sandwiched between two double layers of the sheet motif. The sheets and chains are further connected via aryl ?-? inter-actions [centroid-centroid distances = 3.690?(2) and 3.714?(2)?Å], giving a three-dimensional network.

Bis(2,6-diamino-pyridinium) bis-(hydrogen oxalate) monohydrate.

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. The hydrogen oxalate anions adopt twisted conformations and the dihedral angles between the planes of their carboxyl groups are 31.01?(11) and 63.48?(11)°. In the crystal, the cations, anions and water mol-ecules are linked via O-H?O and N-H?O hydrogen bonds, forming 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.

Bis(2,6-diamino-pyridinium) bis-(pyridine-2,6-dicarboxyl-ato)zincate(II) monohydrate.

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-3,5-dibromo-pyridinium) hexa-bromidostannate(IV).

Project description: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.
