Crystal structure of ethyl (2Z)-2-cyano-3-[(3-methyl-1-phenyl-1H-pyrazol-5-yl)amino]prop-2-enoate
The title compound, C16H16N4O2, crystallizes with two mol-ecules in the asymmetric unit, one of which shows disorder of the acetate group over two sets of sites in a 0.799 (2):0.201 (2) ratio. The phenyl group has a similar but opposite sense of twist relative to the pyrazole ring in the two mol-ecules, as indicated by the syn N-N-Car-Car (ar = aromatic) torsion angles of 39.7 (2) and -36.9 (2)...

In the title indole derivative, C20H18ClNO2, the chloro-phenyl ring is almost perpendicular to the indole moiety, making a dihedral angle of 87.6 (1)°. The mol-ecular packing is stabilized by C-H⋯π inter-actions, which form a C(9) chain motif along [10-1]. In addition, there are weak π-π inter-actions [centroid-centroid distance 3.851 (1) Å] between the chains, involving inversion-related chlor...
متن کاملEthyl (2E)-2-cyano-3-(1-methyl-1H-pyrrol-2-yl)prop-2-enoate
The 15 non-H atoms of the title compound, C(11)H(12)N(2)O(2), are approximately coplanar, the r.m.s. deviation being 0.145 Å. The major deviation from coplanarity is seen in a twist between the ethene (E configuration) and pyrrole rings [C-C-N-C torsion angle = -8.26 (18)°]. The carbonyl O and cyano N atoms are syn to each other. In the crystal, supra-molecular linear tapes linked by C-H⋯O and ...

In the title compound C27H22Cl2N4O2, the pyrazol-5-ol ring makes a dihedral angle of 34.80 (11)° with the phenyl ring to which it is bound, while the pyrazolone ring is inclined at 34.34 (12)° to its attached phenyl ring. In the crystal, N-H⋯O and C-H⋯Cl hydrogen bonds link the mol-ecules into chains along [010]. Inter-molecular π-π inter-actions are observed between the pyrazolone ring and the...
متن کامل(2Z)-3-(3-Bromoanilino)-1-(5-hydroxy-3-methyl-1-phenyl-1H-pyrazol-4-yl)but-2-en-1-one
In the title compound, C(20)H(18)BrN(3)O(2), the central carbonyl group forms amine-N-H⋯O and hy-droxy-O-H⋯O hydrogen bonds, which lead to two fused S(6) rings. The N-bound phenyl ring is coplanar with the five-membered ring to which it is attached [dihedral angle = 5.22 (18)°], but the dihedral angle [33.87 (17)°] between the terminal phenyl and bromo-benzene rings indicates an overall twist i...
