ABSTRACT: The crystal structure of the potential active N-[2-(6-Methoxy-2-oxo-2H-chromen-4-yl)-benzofuran-3-yl]-benzamide (C25H17NO5) (I) has been determined from single crystal X-ray diffraction data. The title compound crystallizes in the monoclinic space group P 21/n, with a = 12.0551(11), b = 9.7853(8), c = 16.6517(16) , β = 90.092(4)o, V = 1964.28(3) 3, Dcalc = 1.391 Mg/m3, Z = 4. In the structure, intermolecular H-bonds lead to the formation of a centrosymmetric dimer of the molecule. There is an intramolecular C7—H7…N1 hydrogen bond forming a closed seven membered ring. There are also intramolecular π-π interactions presented between the 3,6-Dihydro-2H-pyran ring of the chromen moiety [Cg2…Cg2 distance = 3.5812(13) ]. The packing structure is stabilized by these C—H…N, N—H…O hydrogen bonds, C—H… π and π…π interactions.
