Crystal structure of 2-[2-(2,5-dichlorobenzyloxy)-2-(furan-2-yl)ethyl]-2H-indazole

Abstract

In the title compound, C20H16Cl2N2O2, the indazole ring system is approximately planar [maximum deviation = 0.033 (1) Å], 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 = benzyloxy) hydrogen bonds link the molecules into centrosymmetric dimers with graph-set motif R22(12). Weak C—H...π interactions is also observed. Aromatic π–π stacking between the benzene and the pyrazole rings from neighbouring molecules [centroid–centroid distance = 3.8894 (7) Å] further consolidates the crystal packing.
