Abstract

In the title compound, C20H16Cl2N2O2, the indazole ring system is approximately planar [maximum deviation = 0.033 (1) angstrom], its mean plane is oriented at dihedral angles of 25.04 (4) and 5.10 (4)degrees to the furan and benzene rings, respectively. In the crystal, pairs of C-H-ind center dot center dot center dot O-bo (ind = indazole and bo = benzyloxy) hydrogen bonds link the molecules into centrosymmetric dimers with graph-set motif R-2(2) (12). Weak C-H center dot center dot center dot pi interactions is also observed. Aromatic pi-pi stacking between the benzene and the pyrazole rings from neighbouring molecules [centroid-centroid distance = 3.8894 (7) angstrom] further consolidates the crystal packing.
