4-(4-Bromostyryl)-1-methylpyridinium tosylate
In the cation of the title compound, C14H13BrN(+)·C7H7O3S(-), the dihedral angle between the benzene and pyridine rings is 8.34 (11)°. The Br atom is disordered over two positions with site occupancies of 0.74 (2) and 0.26 (2). The mol-ecular structure is stabilized by a weak intra-molecular C-H⋯O inter-actions. The crystal structure exhibits weak C-H⋯O and π-π [centroid-centroid distance = 3.7...

In the title compound, C(14)H(13)ClN(+)·I(-)·H(2)O, the cation is nearly planar and exists in an E configuration; the dihedral angle between the pyridinium and benzene rings is 0.98 (17)°. The cations stack in an anti-parallel manner along the a axis through two π-π inter-actions between the pyridinium and benzene rings [centroid-centroid distances 3.569 (2) and 3.6818 (13) Å, respectively]. Th...

The title salt crystallized as the monohydrate C15H16NO2 (+)·C6H4BrSO3 (-)·H2O. The cation exists in an E conformation with respect to the ethynyl bond and is essentially planar, with a dihedral angle of 6.52 (14)° between the pyridinium and the benzene rings. The hy-droxy and meth-oxy substituents are coplanar with the benzene ring to which they are attached, with an r.m.s. deviation of 0.0116...
متن کامل2-Amino-4-methylpyridinium 2-hydroxy-3,5-dinitrobenzoate
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...
متن کاملSynthesis and Leishmanicidal Activity of 1-[5-(5-nitrofuran-2-yl)-1, 3, 4-thiadiazole-2-yl]-4-benzoylepiperazines
A series of (5-nitrofuran-2-yl)-1, 3, 4-thiadiazole-2-yl derivatives 6a–6e have been synthesized and screened for in vitro anti-leishmanial activity against the promastigote form of L. major. The structure of Schiff bases were confirmed by 1H NMR, IR. Screening results indicate that all of the designed and synthesized final compounds (6a-6e) significantly reduced the viability of promastigotes ...
