5,7-Dimethyl-2,3-dihydro-1H-1,4-diazepin-4-ium picrate
In the cation of the title compound, C(7)H(13)N(2) (+)·C(6)H(2)N(3)O(7) (-), the seven-membered 1,4-diazepine ring forms a twist chair conformation. The two o-nitro groups in the anion are twisted by 35.0 (7) and 36.0 (9)° from the benzene ring. In the crystal, N-H⋯O hydrogen bonds between the cation and anion along with weak C-H⋯O hydrogen bonds produce chains along the b axis. C-H⋯O hydrogen ...
متن کامل(E)-5-(2-Chlorophenyl)-7-ethyl-2-oxo-2,3-dihydro-1H-thieno[2,3-e][1,4]diazepin-4-ium 2,4,6-trinitrophenolate
In the title molecular salt, C(15)H(14)ClN(2)OS(+)·C(6)H(2)N(3)O(7) (-), protonation occurred on the double-bonded N atom. One of the nitro groups shows slight disorder over two orientations, with an occupancy ratio of 0.91:0.09. In the crystal, classical N-H⋯O hydrogen bonds, as well as C-H⋯O contacts connect the components into a three-dimensional network. The seven-membered ring adopts a boa...
متن کامل2-[4-(4,5-Dihydro-1H-imidazol-2-yl)phenyl]-4,5-dihydro-1H-imidazol-3-ium 4-aminobenzoate
In the cation of the title compound, C(12)H(15)N(4) (+)·C(7)H(6)NO(2) (-), the benzene ring makes dihedral angles of 30.51 (9) and 25.64 (9)° with the imidazole and imidazolinium rings, respectively. In the crystal, inter-molecular N-H⋯O and N-H⋯N hydrogen-bonding inter-actions link the mol-ecules into a three-dimensional network.

In the title compound, C(24)H(26)N(4)O(2), the complete mol-ecule is generated by the application of twofold symmetry. The pyrazole ring is approximately planar [r.m.s. deviation = 0.026 Å] and the benzene ring is twisted out of this plane [dihedral angle = 21.94 (7)°]. A twist in the mol-ecule about the central C-C bond [1.566 (3) Å] is also evident [C-C-C-C torsion angle = 44.30 (14)°]. Supra...

In the title compound, 2C(10)H(15)N(4)Se(+)·Cl(-)·OH(-), a singly protonated mol-ecule of the organic selenide participates in hydrogen bonding with neighboring mol-ecules, forming zigzag chains along [001]. The molecule adapts a cis bridging mode with a C-Se-C angle of 102.13 (15)°. π-π stacking inter-actions are observed between the closest pyrazole rings of neighboring chains [centroid-centr...
