چکیده
In the title 2H-pyrazolo-[4,3-c]pyridine derivative, C(32)H(27)Cl(2)N(3), the dihydro-pyrazole ring adopts an envelope conformation and the piperidine fused ring a twisted-chair conformation. Two short intra-molecular C-H⋯Cl contacts are observed. The crystal packing is characterized by dimeric C-Cl⋯π inter-actions involving the 5-benzyl ring, with Cl⋯centroid and closest atomic Cl⋯π distances of 3.778 (2) and 3.366 (4) Å, respectively.
