- Abstract
- C17H14O4, M(r) = 282.30, monoclinic, P2(1)/c, a = 7.402 (1), b = 12.466 (2), c = 14.619 (2) angstrom, beta = 97.25 (1)-degrees, V = 1338.2 (3) angstrom 3, Z = 4, D(x) = 1.40 g cm-3, Cu K-alpha, lambda = 1.54178 angstrom, mu = 8.34 cm-1, F(000) = 592, T = 291 K, R = 0.042 for 1684 observed reflections. The dihedral angle between the benzopyran and the phenyl ring mean planes is 10.5 (5)-degrees.
