title: 4-(9-Anthr-yl)-1-(2,4-dimethoxy-phen-yl)spiro-[azetidine-3,9'-xanthen]-2-one.
abstract: The title compound, C(37)H(27)NO(4), crystallizes with two mol-ecules in the asymmetric unit. The β-lactam ring of each mol-ecule is very nearly planar, with maximum deviations of 0.001 (2) and 0.017 (2) Å in the two mol-ecules. The crystal structure is stabilized by inter-molecular C-H⋯O and C-H⋯N contacts, as well as by weak C-H⋯π inter-actions.
