5-Cyclohexyl-4-methyl-1H-pyrazol-3(2H)-one monohydrate
In the title compound, C(10)H(16)N(2)O·H(2)O, the cyclo-hexane ring is in a chair conformation and its least-squares plane makes a dihedral angle of 53.68 (5)° with the approximately planar pyrazole ring [maximum deviation = 0.034 (1) Å]. Pairs of inter-molecular N-H⋯O hydrogen bonds form inversion dimers between neighbouring pyrazolone mol-ecules, generating R(2) (2)(8) ring motifs. The pyrazo...
متن کامل5-Amino-4-bromo-2,3-dihydro-1H-inden-1-one
In the title compound, C(9)H(8)BrNO, the non-H-atom framework is essentially planar, with a maximum deviation of 0.087 (3) Å. In the crystal, mol-ecules are inter-connected into a three-dimensional network by C-H⋯O and N-H⋯O hydrogen bonds. In addition, C-H⋯π inter-actions and a π-π stacking inter-action, with a centroid-centroid distance of 3.5535 (19) Å, are also observed.
متن کامل3-tert-Butyl-1-(3-nitrophenyl)-1H-pyrazol-5-amine
In the title compound, C(13)H(16)N(4)O(2), the pyrazole ring forms a dihedral angle of 50.61 (6)° with the 3-nitro-phenyl ring. The plane of the nitro group is twisted by 6.8 (7)° out of the plane of the phenyl ring. In the crystal, the mol-ecules are linked by N-H⋯N and N-H⋯O hydrogen bonds, forming sheets in the bc plane. In addition, a weak C-H⋯N inter-action is observed.

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...

The reaction of (E)-tert-butyl 4-[3-(dimethyl-amino)acrylo-yl]piperidine-1-carboxyl-ate with methyl-hydrazine leads to the formation of the title compound, C(14)H(23)N(3)O(2), with a 1-methyl-1H-pyrazol-5-yl substituent. The plane of the pyrazole ring forms a dihedral angle of 33.4 (1)° with the approximate mirror plane of the piperidine ring.
