The crystal structure of the title compound was determined from single crystal X-ray dirt fraction study : C16H16NO3, Mr=271.316, orthorh ombic, Aba2, a=15.750(3), b=13.470(2), c=13.356 (2) A, V=2833A, Z=8, Dx=1.26 Mgm-3, λ(MoK a) =0.71069A, r=0.51mm-2, F(000)=1136, T=291 K, R=0.0414 for 728 unique observed [F≥3e(F)] reflections and 240 parameters. The molecule is nearly planar within 0.2 A with the torsion angle -179(2)°for C(4)-C(7)-C(8)-C(9).The into rmolecular interactions are mainly by van der Waals force with the nearest intermolecular distance 3.647A between O(3) and C(4) translated by half unit along band c-axes.
