چکیده

In the title compound, C(19)H(14)Cl(2)O(4), intra-molecular C-H⋯O and C-H⋯Cl hydrogen bonds generate S(6) and S(5) ring motifs, respectively. In the crystal structure, inter-molecular C-H⋯O inter-actions between symmetry-related mol-ecules involving two methyl-ene groups and an O atom as a bifurcated acceptor generate an R(2) (1)(6) ring motif. In the mol-ecule, one of the furan rings is rotationally disordered by approximately 180° about the single C-C bond to which it is attached; the refined site-occupancy factors are 0.505 (7) and 0.495 (7). The major component of the disordered furan ring and the benzene ring form a dihedral angle of 88.8 (4)°. The dihedral angle between the major disorder component and the other furan ring is 81.9 (4)°. In addition, the crystal structure is stabilized by further inter-molecular C-H⋯O (×2) hydrogen bonds and C-H⋯π inter-actions.
