The crystal structure of 5-phenyl-3,5-diethoxy-2(5H)-furanone(C14H16O4)

The crystal structure of the title compound C14H16O4 has been determined by single crystal X-ray diffraction. The crystal is triclinic system, space g roup P (1) over bar with parameters a = 8.696 (2), b = 8.943 (2), c = 9.379 (2)Angstrom, alpha = 69.28(3), beta = 76.67(3), gamma= 80.28(3)degrees, V= 660.8(3) Angstrom (3), Z=2, M-r =248.28, D-x = 1.248g/cm(3), F(000)=264, mu (MoK alpha)=0.0851 mm(-1). The structure was solved by direct methods and refined by fullmatrix least squares method to the final R=0.061, wR=0.089, X-ray analysis reveals that, there are furanone ring and benzene ring in th e,title compound. The furanone ring constructed by C(1), C(2), C(3), C(4) a nd O(4) is nearly planar, with an average deviation of 0.0078 Angstrom. The two atoms, O(2) and O(3), are in the same plane with furanone ring. The di hedral angle between the furanone ring [C(1)similar toC(4), O(4)] and the b enzene ring [C(11)-C(16)] is 79.39 degrees.
