title: 4-{[5-(4-Chloro-phen-yl)-1-(4-fluoro-phen-yl)-1H-pyrazol-3-yl]carbon-yl}-N-(4-cyano-phen-yl)piperazine-1-carboxamide.
abstract: In the title compound, C(28)H(22)ClFN(6)O(2), the piperazine ring adopts a chair conformation and the least-squares plane through the four coplanar atoms forms dihedral angles of 69.37 (13) and 56.56 (12)°, respectively, with the pyrazole and cyano-phenyl rings. The dihedral angles formed between the pyrazole and the attached fluoro- and chloro-phenyl rings are 34.16 (10) and 73.27 (12)°, respectively. In the crystal, inter-molecular N-H⋯O, C-H⋯N and C-H⋯O hydrogen bonds link the mol-ecules into sheets parallel to the ac plane.
