In the title mol-ecule, C(36)H(25)NO(3), the β-lactam ring is essentially planar, with a dihedral angle of 3.3 (2)° between the two separate three-atom N/C/C planes. The β-lactam ring makes dihedral angles of 28.45 (14), 87.4 (1) and 51.8 (1)° with the mean planes of the benzene, xanthene and anthracene ring systems, respectively. In addition to a weak intra-molecular C-H⋯N hydrogen bond, the crystal structure is stabilized by two weak inter-molecular C-H⋯O hydrogen bonds.
在标题分子C(36)H(25)NO(3)中，β-内酰胺环基本呈平面状，两个独立的三原子N/C/C平面之间的二面角为3.3 (2)°。β-内酰胺环与苯、呫吨和蒽环系统的平均平面的二面角分别为28.45 (14)°、87.4 (1)°和51.8 (1)°。除了一个弱的分子内C-H⋯N氢键外，晶体结构还通过两个弱的分子间C-H⋯O氢键得以稳定。
