摘要

In the title compound, C20H16Cl2N2O2, the indazole ring system is approximately planar [maximum deviation = 0.033?(1)??], its mean plane is oriented at dihedral angles of 25.04?(4) and 5.10?(4)° to the furan and benzene rings, respectively. In the crystal, pairs of C—Hind?Obo (ind = indazole and bo = benz-yloxy) hydrogen bonds link the mol-ecules into centrosymmetric dimers with graph-set motif R22(12). Weak C—H?π inter-actions is also observed. Aromatic π–π stacking between the benzene and the pyrazole rings from neighbouring mol-ecules [centroid–centroid distance = 3.8894?(7)??] further consolidates the crystal packing.
