| Abstract: | The title compound (C11H10N2O3) has been synthesized by the reaction of 4-methoxylphenyl aldehyde with hydantoin under microwave irradiation and its structure was determined by single-crystal X-ray diffraction. The crystal is of triclinic, space group P?with a = 5.346(1), b = 10.212(1), c = 10.368(2) , = 72.34(2), = 75.35(2), = 78.09(2), V = 516.6(2) ?, Mr = 218.21, Z = 2, Dc = 1.403 g/cm3, = 0.104 mm-1, F(000) = 228, R = 0.0442 and wR = 0.1152. X-ray analysis reveals that the dihedral angle between planes 1 (C(8), C(9), C(10), N(1) and N(2)) and 2 (C(1)~C(6)) is 5.45, and intermolecular hydrogen bonding as well as network structure is also found in the crystal. |
