Crystal structure of 3-methylpyridinium picrate: a triclinic polymorph
The title mol-ecular salt, C6H8N(+)·C6H2N3O7 (-) (systematic name: 3-methyl-pyridinium 2,4,6-tri-nitro-phenolate), crystallizes in the triclinic space group P-1. The crystal structure of the monoclinic polymorph (space group P21/n) has been reported [Stilinovic & Kaitner (2011 ▸). Cryst. Growth Des. 11, 4110-4119]. In the crystal, the anion and cation are linked via bifurcated N-H⋯(O,O) hydroge...
متن کاملCrystal structure and hydrogen-bonding patterns in 5-fluorocytosinium picrate
In the crystal structure of the title compound, 5-fluoro-cytosinium picrate, C4H5FN3O+·C6H2N3O7-, one N heteroatom of the 5-fluoro-cytosine (5FC) ring is protonated. The 5FC ring forms a dihedral angle of 19.97 (11)° with the ring of the picrate (PA-) anion. In the crystal, the 5FC+ cation inter-acts with the PA- anion through three-centre N-H⋯O hydrogen bonds, forming two conjoined rings havin...
متن کاملSynthesis, Crystal Growth, Structure, Spectral, Optical and Thermal Characterization of M-Toluidinium Picrate Single Crystal
A new charge transfer molecular complex salt of picric acid with m-toluidine was synthesized and the structure confirmed by single crystal X-ray diffraction (XRD) and NMR spectral analyses. Single crystals of m-toluidinium picrate have been grown by slow solvent evaporation solution growth technique using ethanol as the solvent at ambient temperature. The single crystal XRD analysis of MTP salt...
متن کاملHydrogen bonding in the crystal structure of the molecular salt of pyrazole–pyrazolium picrate
The asymmetric unit of the title organic salt [systematic name: 1H-pyrazol-2-ium 2,4,6-tri-nitro-phenolate-1H-pyrazole (1/1)], H(C3H4N2)2 (+)·C6H2N3O7 (-), consists of one picrate anion and one hydrogen-bonded dimer of a pyrazolium monocation. The H atom involved in the dimer N-H⋯N hydrogen bond is disordered over both symmetry-unique pyrazole mol-ecules with occupancies of 0.52 (5) and 0.48 (5...
متن کاملCrystal structure of a second triclinic polymorph of 2-methylpyridinium picrate
The title mol-ecular salt, C6H8N(+)·C6H2N3O7 (-) (systematic name: 2-methyl-pyridinium 2,4,6-tri-nitro-phenolate), crystallizes with two cations and two anions in the asymmetric unit. In the crystal, the cations are linked to the anions via bifurcated N-H⋯(O,O) hydrogen bonds, generating R 1 (2)(6) graph-set motifs. Numerous C-H⋯O hydrogen bonds are observed between these cation-anion pairs, wh...
