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 pi-pi interactions in 1 and 2 were investigated. Compounds 1 and 2 feature offset face-to-face intermolecular pi-pi interactions with centroid-centroid distances of 3.802(4) angstrom and 3.741(3) angstrom and displacement angles of 8.8(2)degrees and 22.5(5)degrees, respectively.
