Molecular structures and π–π interactions of quercitrin and morusin hydroperoxide

The molecular structures of quercitrin (1) and morusin hydroperoxide (2) were determined by single-crystal X-ray analysis. The intermolecular π–π interactions in 1 and 2 were investigated. Compounds 1 and 2 feature offset face-to-face intermolecular π–π interactions with centroid–centroid distances of 3.802(4) Å and 3.741(3) Å and displacement angles of 8.8(2)° and 22.5(5)°, respectively.
