3-(2,4-Dichloro­phen­yl)-1,5-di-2-furylpentane-1,5-dione

In the title compound, C(19)H(14)Cl(2)O(4), intra­molecular C—H⋯O and C—H⋯Cl hydrogen bonds generate S(6) and S(5) ring motifs, respectively. In the crystal structure, inter­molecular C—H⋯O inter­actions between symmetry-related mol­ecules involving two methyl­ene groups and an O atom as a bifurcate...

Sumario:In the title compound, C(19)H(14)Cl(2)O(4), intra­molecular C—H⋯O and C—H⋯Cl hydrogen bonds generate S(6) and S(5) ring motifs, respectively. In the crystal structure, inter­molecular C—H⋯O inter­actions between symmetry-related mol­ecules involving two methyl­ene groups and an O atom as a bifurcated acceptor generate an R (2) (1)(6) ring motif. In the mol­ecule, 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 inter­molecular C—H⋯O (×2) hydrogen bonds and C—H⋯π inter­actions.
