(1E,4E)-1,5-Bis(2,4,5-trimethoxy­phen­yl)penta-1,4-dien-3-one

There are three mol­ecules 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 benz...

description There are three mol­ecules 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 mol­ecule, whereas the corresponding pairs of angles in the other two mol­ecules are 10.34 (9)/17.46 (8)° and 7.87 (8)/13.33 (8)°. In the crystal, mol­ecules are linked by inter­molecular C—H⋯O and C—H⋯π weak inter­actions into a three-dimensional network. Finally, π–π inter­actions [centroid⋯centroid distances = 3.5984 (10) and 3.5545 (10) Å] are observed.
