4-(4-Carboxy-benz-yl)-1-methyl-piperazin-1-ium picrate.

ABSTRACT: The title compound, C(13)H(19)N(2)O(2) (+)·C(6)H(2)N(3)O(7) (-), is a salt obtained by cocrystallization of 4-[(4-methyl-piperazin-1-yl)meth-yl]benzoic acid and picric acid. The cations adopt an 'L-shaped' conformation and are linked into chains along [010] by O-H?N hydrogen bonds. The NH group of each piperazinium ring forms a hydrogen bond to the phenolate O atom of a picrate anion, and the picrate anions form face-to-face contacts with an inter-planar separation of 3.023?(1)?Å.

4-(2,3-Di-chloro-phen-yl)piperazin-1-ium picrate.

Project description:The title compound, C6H2N3O7 -·C10H13Cl2N2 +, crystallizes with one 1-(2,3-di-chloro-phen-yl)piperazine (DP) cation and one picrate (PA) anion in the asymmetric unit. In the crystal structure, the DP cation and PA anion are inter-connected via several N-H⋯O and C-H⋯O hydrogen bonds. The DP cation and PA anion are further connected through C-Cl⋯π [3.8201 (4), 3.7785 (4) Å] and N-O⋯π [3.7814 (4) Å] inter-actions. The DP cations are further inter-connected via a weak inter-molecular Cl⋯Cl [3.2613 (4) Å] halogen-halogen inter-action. The combination of these supra-molecular inter-actions leads to a herringbone like supra-molecular architecture.

In the crystal, N-H?O hydrogen bonds as well as C-H?O contacts connect the components into a three-dimensional network.

Crystal structure of 1-(3-chloro-phen-yl)piperazin-1-ium picrate-picric acid (2/1).

Project description:The title salt {systematic name: bis-[1-(3-chloro-phen-yl)piperazinium 2,4,6-tri-nitro-phenolate]-picric acid (2/1)}, 2C10H14ClN2 (+)·2C6H5N3O7 (-)·C6H6N3O7, crystallized with two independent 1-(3-chloro-phen-yl)piperazinium cations, two picrate anions and a picric acid mol-ecule in the asymmetric unit. The six-membered piperazine ring in each cation adopts a slightly distorted chair conformation and contains a protonated N atom. In the picric acid mol-ecule, the mean planes of the nitro groups in the ortho-, meta-, and para-positions are twisted from the benzene ring by 31.5 (3), 7.7 (1), and 3.8 (2)°, respectively. In the anions, the dihedral angles between the benzene ring and the ortho-, meta-, and para-nitro groups are 36.7 (1), 5.0 (6), 4.8 (2)°, and 34.4 (9), 15.3 (8), 4.5 (1)°, respectively. The nitro group in one anion is disordered and was modeled with two sites for one O atom with an occupancy ratio of 0.627 (7):0.373 (7). In the crystal, the picric acid mol-ecule inter-acts with the picrate anion through a trifurcated O-H⋯O four-centre hydrogen bond involving an intra-molecular O-H⋯O hydrogen bond and a weak C-H⋯O inter-action. Weak inter-molecular C-H⋯O inter-actions are responsible for the formation of cation-anion-cation trimers resulting in a chain along [010]. In addition, weak C-H⋯Cl and weak π-π inter-actions [centroid-centroid distances of 3.532 (3), 3.756 (4) and 3.705 (3) Å] are observed and contribute to the stability of the crystal packing.

4-(4-Methyl-phenyl-sulfon-yl)piperazin-1-ium tri-fluoro-acetate.

Project description:In the title salt, C11H17N2O2S(+)·CF3COO(-), the cation is protonated at the secondary piperazine N atom. The dihedral angle between the benzene ring and the piperazine mean plane is 85.54 (10)°. In the crystal, cations and anions are connected by two types of strong N-H⋯O hydrogen bonds into chains extending along [101]. The chains are further assembled into (10-1) layers via stacking inter-actions between benzene rings of the cations [centroid-centroid distance = 3.7319 (13) Å] and a C-H⋯O inter-action involving a piperazine C-H group and a sulfonyl O atom. Another C-H⋯O inter-action between the piperazine ring and the sulfonyl group connects the ions into a three-dimensional network.

In the crystal, weak aromatic ?-? stacking [centroid-centroid distance = 3.599?(15)?Å] consolidates the packing. In addition, an intra-molecular N-H?N hydrogen bond is observed.

Project description:The title salt, C13H11N2O2 (+)·C6H2N3O7 (-), is the unexpected product of a domino reaction of 3-cyano-methyl-1-methyl-imidazolium chloride with salicylic aldehyde in the presence of picric acid. In the cation, the 1H-imidazole ring is twisted by 63.2 (1)° from the 2H-chromen plane. In the crystal, cations and anions are alternately stacked along the a axis through π-π stacking inter-actions between the almost parallel aromatic rings [centroid-centroid distances = 3.458 (2) and 3.678 (2) Å]. The stacks are further linked by C-H⋯O hydrogen bonds into a two-tier layer parallel to (001).
