In the title salt, C11H14N3O+·C7H5O3
−, the phenyl ring of the cation is oriented at an angle of 67.0 (1)° with respect to the five-membered pyrazolone ring. The carboxyl­ate plane of the anion is twisted out from the plane of the aromatic ring at an angle of 13.7 (3)°. In the crystal, the cations form hydrogen-bonded dimers with an R
2(10) ring motif. The salicylate anion has an intra­molecular O—H⋯O hydrogen bond.

    ABSTRACT: Interaction of salicylic acid (saH) with the azacycles piperidine (pipe) and meso-5,7,7,12,12,14-hexamethyl-1,4,8,11-tetraazacyclotetradecane (teta) and with the aza-crown ethers aza-12-crown-4 (A12C4), benzoaza-15-crown-5 (BA15C5), aza-18-crown-6 (A18C6), and diaza-18-crown-6 (DA18C6) afforded the proton-transfer complexes (organic salts) of compositions [pipeH][sa], [tetaH2][sa]2, [A12C4H][sa], [BA15C5H][sa], [A18C6H][sa]·2H2O, and [DA18C6H2][sa]2·3H2O, whose structures were determined by a single crystal X-ray method. These products were also obtained by the same synthetic conditions starting from acetylsalicylic acid (aspirin) as a result of hydrolysis. The charge-assisted N−H···O hydrogen-bond provides the main driving force for direct binding of sa with cyclic azonia cations. The crystal packing is also supported by weak C−H···O hydrogen bonding and edge-to-face π···π intermolecular interactions.

    ABSTRACT: In the crystal structure of the title compound, C12H14N2 2+·2C7H5O3 −, the cations and anions are linked via N—H⋯O hydrogen bonds and weak inter­molecular C—H⋯O inter­actions also occur. π–π stacking is observed between the nearly parallel benzene and pyridine rings [dihedral angle = 6.03 (8)°], the centroid–centroid separation being 3.7546 (16) Å. The 4,4′-(ethane-1,2-diyl)dipyridinium cation is centrosymmetric and the mid-point of the ethyl­ene C—C bond is located on an inversion center. An intra­molecular O—H⋯O hydrogen bond occurs in the anion.

    ABSTRACT: In the title compound, C(11)H(14)N(3)O(+)·Cl(-)·CH(4)N(2)S, the components are connected into a two-dimensional polymeric structure parallel to (001) via N-H⋯Cl, N-H⋯O, N-H⋯S and C-H⋯S hydrogen bonds. The dihedral angle between the phenyl and 2,3-dihydro-1H-pyrazole rings is 44.96 (7)°.
