Abstract :

The title compound, C12H10N2 O2, represents an orthorhombic system, space group pbca with a = 9.4339 (10) Å, b = 9.6549 (9) Å, c = 23.418 (3) Å, V = 2133.0 (4) Å3 , Z = 8, F(000) = 896, Dx = 1.334 Mg m−3, R= 0.041 and wR= 0.136, T = 293 K. In the title compound, C12H10N2 O2, the dihedral angle between the benzene and furan rings is 55.21(7)°. The benzamide fragment and furan ring are located on the opposite sides of the C=N bond, showing an E conformation. In the crystal, molecules are linked via intermolecular bifurcated (N,C)—H…O hydrogen bonds, generating an R1 2 (6) ring motif, forming chains along the c axis. These chains are linked into a three–dimensional network by C—H…N and C—H…π interactions. The crystal structure of the title compound was characterized by X–ray studies and spectroscopic FTIR, 1 H and 13C NMR techniques.
