Abstract

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 benzene rings in one mol-ecule, whereas the corresponding values are 8.42 (16) and 6.18 (16)° in the other. In the crystal, mol-ecules are arranged into chains along the c-axis direction. Adjacent chains are inter-linked by weak inter-molecular C-H⋯O inter-actions. The crystal is further stabilized by C-H⋯π inter-actions.
