چکیده
There are three mol-ecules in the asymmetric unit of the title compound, C(23)H(26)O(7), in which the dihedral angles between two benzene rings are 4.34 (9), 18.11 (8) and 8.54 (8)°. The central penta-1,4-dien-3-one fragment makes dihedral angles of 3.95 (9) and 3.32 (16)° with the two adjacent benzene rings in one mol-ecule, whereas the corresponding pairs of angles in the other two mol-ecules are 10.34 (9)/17.46 (8)° and 7.87 (8)/13.33 (8)°. In the crystal, mol-ecules are linked by inter-molecular C-H⋯O and C-H⋯π weak inter-actions into a three-dimensional network. Finally, π-π inter-actions [centroid⋯centroid distances = 3.5984 (10) and 3.5545 (10) Å] are observed.

There are two crystallograpically independent mol-ecules in the asymmetric unit of the title bis-chalcone derivative, C25H32N2O. Both mol-ecules are twisted with a dihedral angle between the two substituted benzene rings of 11.19 (16)° in one mol-ecule and 14.40 (15)° in the other. The central penta-1,4-dien-3-one fragments make dihedral angles of 8.49 (17) and 4.26 (17)° with the two adjacent ...
