8‐tert‐Butyl‐7‐(4‐chlorophenyl)‐10‐phenyl‐5,6‐dihydro‐10H‐benzo[h]pyrazolo[3,4‐b]quinoline

The title compound, C₃₀H₂₆ClN₃, crystallizes with Z′ = 3 in the P space group. The three independent molecules have very similar, although not identical, conformations, with almost perfect screw‐boat forms adopted by the non‐aromatic carbocyclic rings. Four independent C—H...π(arene) hydrogen bonds link the molecules into centrosymmetric six‐component aggregates.
