چکیده
In the structure of the title salt, C(12)H(10)N(3)O(4) (+)·C(7)H(3)N(2)O(7) (-), the cations and the anions are linked by a single N(+)-H⋯O(carbox-yl) hydrogen bond, the discrete cation-anion unit having no inter-molecular associations other than weak cation-anion aromatic ring π-π inter-actions [ring centroid separation = 3.7320 (14) Å] and a number of weak inter-unit aromatic C-H⋯O contacts. An intramolecular C-H⋯O hydrox-yl-carboxyl hydrogen bond occurs in the anion.

In the cation of the title salt, [Ag(C(12)H(6)N(2)O(2))(2)](C(7)H(3)N(2)O(7)), the Ag(I) atom is coordinated in a distorted tetra-hedral geometry by four N atoms from two 1,10-phenanthroline-5,6-dione ligands, while the 3,5-dinitro-salicylate anion has only a short contact [2.847 (6) Å] between one of its O atoms and the Ag(I) atom. The dihedral angle between the two 1,10-phenanthroline-5,6-dio...

In the title mol-ecular salt, C(6)H(9)N(2) (+)·C(7)H(3)N(2)O(7) (-), the 2-amino-5-methyl-pyridinium cation is essentially planar, with a maximum deviation of 0.023 (1) Å. There is an intra-molecular O-H⋯O hydrogen bond in the 3,5-dinitro-salicylate anion, which generates an S(6) ring motif. In the crystal, the protonated N atom and the 2-amino group are hydrogen bonded to the carboxyl-ate O at...

In the structure of the title salt, 2C(12)H(10)N(3)O(4) (+)·C(12)H(8)O(6)S(2) (2-)·3H(2)O, determined at 173 K, the biphenyl-4,4'-disulfonate dianions lie across crystallographic inversion centres with the sulfonate groups inter-acting head-to-head through centrosymmetric cyclic bis-(water)-bridged hydrogen-bonding associations [graph set R(4) (4)(11)], forming chains. The 2-(2,4-dinitro-benz-y...

In the anion of the title mol-ecular salt, C(6)H(9)N(2) (+)·C(7)H(3)N(2)O(7) (-), the two nitro groups are twisted from the attached benzene ring with dihedral angles of 27.36 (10) and 4.86 (11)°. The anion is stabilized by an intra-molecular O-H⋯O hydrogen bond, which generates an S(6) ring motif. In the crystal, the cations and anions are linked by N-H⋯O and C-H⋯O inter-actions and are furthe...

The crystal structure of the title compound, C(7)H(10)N(+)·C(7)H(3)N(2)O(6) (-), displays N-H⋯O hydrogen bonding between the ammonium groups and the O atoms of the 3,5-dinitro-benzoate anions. Inter-molecular C-H⋯O inter-actions further stabilize the packing. An O atom of each of the nitro groups is disordered over two sites with site occupancy factors of 0.59 (5) and 0.41 (6).
