چکیده
In the title compound, C(22)H(18)N(4)O(2)S, the seven-membered ring generated by an intra-molecular N-H⋯O hydrogen bond adopts an envelope conformation in both of the two independent mol-ecules in the asymmetric unit. In the crystal, mol-ecules are linked into C(9) chains along [100] by N-H⋯O hydrogen bonds. The mol-ecules are also weakly linked by C-H⋯O and C-H⋯N inter-actions, forming dimers with edge-connected R(2) (2)(9) rings. The dimers are inter-linked by further weak C-H⋯N hydrogen bonds into chains along [010].

In the title compound, C19H17Cl2N3O2, the amide group is planar and, through N-H⋯O hydrogen bonding to an adjoining mol-ecule, forms dimers of the R2(2)(10) type. As a result of steric repulsion, the amide group is rotated with respect to both the dichloro-phenyl and 2,3-dihydro-1H-pyrazol-4-yl rings, making dihedral angles of 71.63 (11) and 57.93 (10)°, respectively. The dihedral angle between...
