Orphenadrinium picrate picric acid.

ABSTRACT: The asymmetric unit of the title compound N,N-dimethyl-2-[(2-methyl-phen-yl)phenyl-meth-oxy]ethanaminium picrate picric acid, C(18)H(24)NO(+)·C(6)H(2)N(3)O(7) (-)·C(6)H(3)N(3)O(7), contains one orphenadrinium cation, one picrate anion and one picric acid mol-ecule. In the orphenadrine cation, the two aromatic rings form a dihedral angle of 70.30?(7)°. There is an intra-molecular O-H?O hydrogen bond in the picric acid mol-ecule, which generates an S(6) ring motif. In the crystal structure, the orphenadrine cations, picrate anions and picric acid mol-ecules are connected by strong inter-molecular N-H?O hydrogen bonds, ??? inter-actions between the benzene rings of cations and anions [centroid-centroid distance = 3.5603?(9)?Å] and weak C-H?O hydrogen bonds, forming 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 ?-? 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.

Benzamide-picric acid (1/1).

Project description:In the title compound, C(7)H(7)NO·C(6)H(3)N(3)O(7), one of the nitro groups of the picric acid mol-ecule lies in the plane of the attached benzene ring [dihedral angle = 1.4 (1)°] while the other two are twisted away by 9.9 (1) and 30.3 (1)°. In the benzamide mol-ecule, the amide group is almost coplanar with the benzene ring [dihedral angle = 4.4 (1)°]. An intra-molecular O-H⋯O hydrogen bond generates an S6 ring motif. In the crystal, mol-ecules are linked into a ribbon-like structure along the b axis by O-H⋯O and N-H⋯O inter-molecular hydrogen bonds. In addition, C-H⋯O hydrogen bonds and short O⋯O contacts [2.828 (2) Å] are observed.

4-Nitro-aniline-picric acid (2/1).

Project description:In the title adduct, C(6)H(3)N(3)O(7)·0.5C(6)H(6)N(2)O(2), the complete 4-nitro-aniline mol-ecule is generated by a crystallographic twofold axis with two C atoms and two N atoms lying on the axis. The mol-ecular components are linked into two dimensional corrugated layers running parallel to the (001) plane by a combination of inter-molecular N-H?O and C-H?O hydrogen bonds. The phenolic oxygen and two sets of nitro oxygen atoms in the picric acid were found to be disordered with occupancies of 0.81?(2):0.19?(2) and 0.55?(3):0.45?(3) and 0.77?(4):0.23?(4), respectively.

Triptycene-Derived Photoresponsive Fluorescent Azo-Polymer as Chemosensor for Picric Acid Detection.

Project description:Two new triptycene-based azobenzene-functionalized polymers (TBAFPs) have been synthesized using the well-known Pd-catalyzed Sonogashira cross-coupling polycondensation reaction between 2,6-diethynyltriptycene and (meta or para) dibromo-azobenzenes. Enhancement of the fluorescent emission intensity was observed upon trans → cis isomerization of -N=N- linkage in TBAFPs. The cis-lifetime of TBAFP1 is rather long (greater than 2 days). The resulting materials were tested as a potential chemosensor for the detection of picric acid (PA)-a water pollutant as well as chemical constituent of explosives used in warfare. PA was found to interact strongly with TBAFPs, which led to significant quenching of the latter's fluorescence emission intensities. The binding constants are in the order of 105 M-1. TBAFPs were also able to detect PA in nanomolar concentrations.

Nitrite elimination and hydrolytic ring cleavage in 2,4,6-trinitrophenol (picric acid) degradation.

Project description:Two hydrogenation reactions in the initial steps of degradation of 2,4,6-trinitrophenol produce the dihydride Meisenheimer complex of 2,4,6-trinitrophenol. The npdH gene (contained in the npd gene cluster of the 2,4,6-trinitrophenol-degrading strain Rhodococcus opacus HL PM-1) was shown here to encode a tautomerase, catalyzing a proton shift between the aci-nitro and the nitro forms of the dihydride Meisenheimer complex of 2,4,6-trinitrophenol. An enzyme (which eliminated nitrite from the aci-nitro form but not the nitro form of the dihydride complex of 2,4,6-trinitrophenol) was purified from the 2,4,6-trinitrophenol-degrading strain Nocardioides simplex FJ2-1A. The product of nitrite release was the hydride Meisenheimer complex of 2,4-dinitrophenol, which was hydrogenated to the dihydride Meisenheimer complex of 2,4-dinitrophenol by the hydride transferase I and the NADPH-dependent F(420) reductase from strain HL PM-1. At pH 7.5, the dihydride complex of 2,4-dinitrophenol is protonated to 2,4-dinitrocyclohexanone. A hydrolase was purified from strain FJ2-1A and shown to cleave 2,4-dinitrocyclohexanone hydrolytically to 4,6-dinitrohexanoate.

A Highly-Sensitive Picric Acid Chemical Sensor Based on ZnO Nanopeanuts.

Project description:Herein, we report a facile synthesis, characterization, and electrochemical sensing application of ZnO nanopeanuts synthesized by a simple aqueous solution process and characterized by various techniques in order to confirm the compositional, morphological, structural, crystalline phase, and optical properties of the synthesized material. The detailed characterizations revealed that the synthesized material possesses a peanut-shaped morphology, dense growth, and a wurtzite hexagonal phase along with good crystal and optical properties. Further, to ascertain the useful properties of the synthesized ZnO nanopeanut as an excellent electron mediator, electrochemical sensors were fabricated based on the form of a screen printed electrode (SPE). Electrochemical and current-voltage characteristics were studied for the determination of picric acid sensing characteristics. The electrochemical sensor fabricated based on the SPE technique exhibited a reproducible and reliable sensitivity of ~1.2 μA/mM (9.23 μA·mM-1·cm-2), a lower limit of detection at 7.8 µM, a regression coefficient (R²) of 0.94, and good linearity over the 0.0078 mM to 10.0 mM concentration range. In addition, the sensor response was also tested using simple I-V techniques, wherein a sensitivity of 493.64 μA·mM-1·cm-2, an experimental Limit of detection (LOD) of 0.125 mM, and a linear dynamic range (LDR) of 1.0 mM-5.0 mM were observed for the fabricated picric acid sensor.

Chlorimipraminium picrate.

Project description:The title compound {systematic name: 3-chloro-5-[3-(dimethyl-amino)prop-yl]-10,11-dihydro-5H-dibenz[b,f]azepinium picrate}, C(19)H(24)ClN(2) (+)·C(6)H(2)N(3)O(7) (-), crystallizes with two independent cation-anion pairs in the asymmetric unit. The chlorimipraminium cation contains two benzene rings (one with a chloro substituent) fused to a V-shaped seven-membered azepine ring whose mean planes are separated by 61.1?(0) and 66.5?(8)° with a 3-(dimethyl-amino)propyl group extending away from the apex of this ring. In the picrate anion, the mean planes of the two o-NO(2) groups in each anion are twisted by 3.7?(2)/31.9?(3) and 31.3?(1)/11.4?(0)°, respectively, with respect to the mean plane of the six-membered benzene ring. The phenolate O atoms are bent slightly away from the mean plane of the benzene ring. The mean planes of the p-NO(2) groups are twisted by 6.6?(1) and 2.88°, respectively, from the mean plane of the benzene ring. The crystal packing features bifurcated N-H?(O,O) inter-molecular hydrogen-bond inter-action, which connects each cation-anion pair. Additional ?-? ring and C-H?? weak inter-molecular inter-actions are also observed.
