Ethyl 5-[(2,3-dimethyl-5-oxo-1-phenyl-2,5-dihydro-1H-pyrazol-4-yl)iminomethyl]-3,4-dimethyl-1H-pyrrole-2-carboxylate
In the title compound, C(21)H(24)N(4)O(3), the mol-ecule has an E configuration about the imine C=N double bond. Inter-molecular N-H⋯O hydrogen bonds assemble mol-ecules into centrosymmetric dimers.

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, C(16)H(18)N(2)O(6), the dihedral angle between the aromatic ring planes is 8.11 (6)°. One of the O atoms is disordered over two sites of equal occupancy. In the crystal structure, aromatic π-π stacking [centroid-to-centroid separation = 3.5503 (8) Å] helps to consolidate the packing.

In the title compound, C(23)H(23)N(5)O(2), an intra-molecular N-H⋯O hydrogen bond generates an S(6) ring, and the dihedral angle between the pyrazole rings is 48.42 (8)°. The dihedral angles between the pyrazole rings and their attached phenyl rings are 10.06 (8) and 47.53 (8)°.

In the title compound, C(26)H(23)N(5)O(2)S, an intra-molecular N-H⋯O inter-action generates an S(6) ring. The essentially planar S(6) and pyrazole rings [maximum deviations = -0.0270 (14) and 0.0195 (15) Å, respectively] are nearly coplanar, making a dihedral angle of 3.94 (6)°. The S(6) ring makes dihedral angles of 23.79 (6), 78.53 (6) and 67.91 (6)° with the pyrazolone ring, the pyrazole rin...
