2-Amino-3-carb-oxy-pyrazin-1-ium dihydrogen phosphate.

ABSTRACT: In the crystal structure of the title compound, C(5)H(6)N(3)O(2) (+)·H(2)PO(4) (-), the dihydrogen phosphate anions are linked through short O-H?O hydrogen bonds, forming infinite double chains running parallel to the b axis. Centrosymetric N-H?O hydrogen-bonded cationic dimers form bridges between these chains by means of inter-molecular N-H?O and O-H?O hydrogen bonds, leading to a two-dimensional network parallel to (100) in which R(3) (3)(12), R(4) (3)(10) R(2) (2)(8) and C(4) graph-set motifs are generated. Weak inter-molecular C-H?O hydrogen bonds connect these layers, forming a three-dimensional network.

In the crystal structure of the title compound, C(5)H(6)N(3)O(2) (+)·H(2)PO(4) (-), the dihydrogen phosphate anions are linked through short O-H⋯O hydrogen bonds, forming infinite double chains running parallel to the b axis. Centrosymetric N-H⋯O hydrogen-bonded cationic dimers form bridges between these chains by means of inter-molecular N-H⋯O and O-H⋯O hydrogen bonds, leading to a two-dimensional network parallel to (100) in which R(3) (3)(12), R(4) (3)(10) R(2) (2)(8) and C(4) graph-set motif ...[more]

Project description:The crystal structure of the title compound, 2C(5)H(6)N(3)O(2) (+)·SO(4) (2-)·2H(2)O, displays a variety of N-H?O and O-H?O hydrogen bonds in which all potential donors and acceptors are involved.

Project description:The asymmetric unit of the title compound, C(5)H(6)N(3)O(2) (+)·ClO(4) (-)·2C(5)H(5)N(3)O(2)·H(2)O, comprises two symmetry-independent zwitterions, one cation, one perchlorate anion and one water mol-ecule. In the crystal, the three different types of organic entities are linked by N-H?O and N-H?N hydrogen bonds, forming undulating sheets parallel to (1-10). These sheets are in turn connected by O-H?N and O-H?O hydrogen bonds involving perchlorate anions and water mol-ecules, forming a three-dimensional network. Intra-molecular N-H?O and weak inter-molecular C-H?O hydrogen bonds are also present.

Project description:The cation of the title compound, C(7)H(7)N(2)S(+)·H(2)PO(4) (-), is almost planar (r.m.s deviation = 0.017?Å for all non-H atoms). In the crystal structure, the cations and anions are connected by N-H?O and O-H?O hydrogen bonds, with ?-? stacking inter-actions between neighbouring 1,3-thia-zole and benzene rings [centroid-centroid distance = 3.5711?(11)?Å], forming a three-dimensional network.

3-Amino-pyridin-1-ium 3-carb-oxy-benzo-ate.

Project description:In the title organic salt, C(5)H(7)N(2) (+)·C(8)H(5)O(4) (-), the carb-oxy-lic group is nearly coplanar with the benzene ring [dihedral angle 1.9 (4)°] whereas the carboxyl-ate group is twisted relative to the benzene ring by 13.6 (4)°. In the crystal, N-H⋯O and O-H⋯O hydrogen bonds connect the components into a three-dimensional framework consisting of stacks of alternating pairs of anions and cations exhibiting π-π stacking inter-actions with centroid-centroid distances in the range 3.676 (2)-3.711 (1) Å. The π-π stacks extend along [110] and [-110].

Project description:In the title salt, C(8)H(16)N(2)O(4) (2+)·2H(2)PO(4) (-)·2H(2)O, the piperazine ring is located around an inversion center and adopts a chair conformation. The dihydrogen phosphate anions and free water mol-ecules are linked via O-H⋯O hydrogen bonds into two-dimensional hydrogen-bonding layers, which are further connected through O-H⋯O and N-H⋯O hydrogen bonds involving the protonated piperazine into a three-dimensional supra-molecular network.

5-Amino-3-carb-oxy-1H-1,2,4-triazol-4-ium nitrate monohydrate.

Project description:The two-dimensional crystal packing of the title compound, C(3)H(5)N(4)O(2) (+)·NO(2) (-)·H(2)O, results from the stacking of well separated layers (i.e. with nothing between the layers) parallel to the (-113) plane in which adjacent cations adopt a head-to-head arrangement such that two -COOH groups are linked via two water mol-ecules (the water O atom behaves simultaneously as donor and acceptor of hydrogen bonds) and two -NH(2) groups are linked through two nitrate anions. This arrangement leads to alternating hydro-philic and hydro-phobic zones in which O-H?O and N-H?O hydrogen bonds, respectively, are observed.

5-Amino-6-methyl-quinolin-1-ium 3-carb-oxy-propano-ate.

Project description:The asymmetric unit of the title salt, C10H11N2 (+)·C4H5O4 (-), consists of two independent 5-amino-6-methyl-quinolin-1-ium cations and two 3-carb-oxy-propano-ate anions. Both cations are protonated at the pyridine N atoms and are essentially planar, with maximum deviations of 0.026 (3) and 0.016 (2) Å. In the crystal, the cations and anions are linked via N-H⋯O and O-H⋯O hydrogen bonds, forming a layer parallel to the ab plane. In the layer, weak C-H⋯O hydrogen bonds and π-π stacking inter-actions, with centroid-to-centroid distances of 3.7283 (15) and 3.8467 (15) Å, are observed. The crystal structure also features weak C-H⋯O hydrogen bonds between the layers.

4-Phenyl-piperazin-1-ium dihydrogen phosphate.

Project description:The title compound, C(10)H(15)N(2) (+)·H(2)PO(4) (-), is built up from 4-phenyl-piperazin-1-ium cations and dihydrogen phosphate anions. The inter-connection between two adjacent anions is assured by two strong O-H⋯O hydrogen bonds, which lead to the formation of infinite wave-like chains which spread along the a axis. The organic cations connect these chains via N-H⋯O hydrogen bonds. The crystal cohesion and stability are ensured by electrostatic and van der Waals inter-actions which, together with N-H⋯O and O-H⋯O hydrogen bonds, build up a two-dimensional network.

4-Carb-oxy-pyridin-1-ium 2,4,5-tri-carb-oxy-benzoate monohydrate.

Project description:The title hydrated salt, C6H6NO2 (+)·C10H5O8 (-)·H2O, was isolated from the 1:1 cocrystallization of benzene-1,2,4,5-tetra-carb-oxy-lic acid and isonicotinic acid in ethanol solution. In the crystal, the cation is close to planar [r.m.s. deviation = 0.085 Å for the nine fitted atoms; the C-C-C-O(carbon-yl) torsion angle = -8.7 (4)°], but twists are evident in the anion, with all but the carb-oxy-lic acid group diagonally opposite the carboxyl-ate group being significantly twisted out of the plane of the benzene ring [C-C-C-O(carbon-yl) torsion angles = -118.1 (2), -157.6 (2), 4.3 (3) and 77.3 (3)°]. In the crystal, the ions and water mol-ecules are consolidated into a three-dimensional architecture by O-H⋯O and N-H⋯O hydrogen bonding along with C-H⋯O inter-actions.
