2,2-Dimethyl-2,3-dihydro-1H-perimidine
The title compound, C(13)H(14)N(2), was obtained from reaction of diaminona-phthalene with acetone. In both independent mol-ecules in the asymmetric unit, the tricyclic perimidine consists of a planar (r.m.s. deviations = 0.0125 and 0.0181 Å) naphthalene ring system and an envelope conformation C(4)N(2) ringwith the NCN group hinged with respect to the naph-thalene backbone by 36.9 (2) and 41.3...

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 ...

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...
متن کامل1,5-Dimethyl-3-oxo-2-phenyl-2,3-dihydro-1H-pyrazol-4-aminium bromide monohydrate
In the title hydrated mol-ecular salt, C(11)H(14)N(3)O(+)·Br(-)·H(2)O, the Br(-) anion is split and appears as two independent half-occupied Br(-) anions on twofold rotation axes. The dihedral angle between the phenyl ring and the mean plane of the 2,3-dihydro-1H-pyrazole ring (r.m.s. devation = 0.014 Å) is 62.43 (7)°. In the crystal, the components are connected via O-H⋯Br and N-H⋯O hydrogen b...

In the title compound, C(12)H(13)N(3)O(2), the dihedral angle between the pyrazole and benzene rings is 50.0 (3)°. In the crystal, mol-ecules are linked by inter-molecular N-H⋯O hydrogen bonds to form a three-dimensional network. Two weak C-H⋯π inter-actions reinforce the crystal packing.
