摘要：

C19H19NO4, M(r) = 325.36, orthorhombic, P2(1)2(1)2(1), a = 8.293 (5), b = 8.462 (5), c = 22.80 (1) angstrom, V = 1600 (1) angstrom 3, Z = 4, D(x) = 1.350 Mg m-3, lambda(Mo K-alpha) = 0.7107 angstrom, mu = 0.088 mm-1, F(000) = 688, T = 293 (1) K, R = 0.063 for 1523 reflections with I > 3.5-sigma(I). The asymmetric C atom C5 has an S configuration. Ring B exhibits a half-chair conformation, while the form of the C ring is nearest that of a screw-boat. The dihedral angle between the two phenyl rings A and D is 34.4 (2)-degrees. The molecules are held together by hydrogen bonds forming an infinite chain along the b axis.
