title: 4-(9-Anthr-yl)-1-(3-bromo-phen-yl)spiro-[azetidine-3,9'-xanthen]-2-one.
abstract: In the title mol-ecule, C(35)H(22)BrNO(2), the four-membered ring of the β-lactam unit is nearly planar [maximum deviation = 0.003 (3) Å] and makes dihedral angles of 87.07 (15), 59.80 (16) and 20.81 (19)°, respectively, with the xanthene system, the anthracene system and the bromo-substituted benzene ring. The mol-ecular conformation is stabilized by weak intra-molecular C-H⋯O and C-H⋯N hydrogen bonds. The crystal structure features weak C-H⋯π inter-actions.
