ABSTRACT: The ?-lactam ring of the title compound, C(35)H(23)NO(2), is nearly planar with a maximum deviation of 0.003?(3)?Å from the mean plane. It makes dihedral angles of 17.4?(2), 85.22?(17) and 65.39?(16)°, respectively, with the phenyl, xanthene and anthracene ring systems. In the crystal structure, there are intra-molecular C-H?O and C-H?N contacts and mol-ecules are also linked by C-H?? inter-actions.

4-(9-Anthr-yl)-1-(2-methoxy-phen-yl)spiro-[azetidin-3,9'-xanthen]-2-one.

Project description:The stabilized conformation of the title compound, C(36)H(25)NO(3), 4-(9-anthryl)-1-(2-methoxyphenyl)-spiro[azetid-in-3,9'-xanthen]-2-one, may be compared with that of the isomeric compound 4-(9-anthr-yl)-1-(4-methoxy-phen-yl)spiro-[azetidin-3,9'-xanthen]-2-one. In the title isomer, the meth-oxy group is slightly twisted out of the plane of the attached benzene ring, with a C-O-C-C torsion angle of 31.5?(2)°. Its ?-lactam ring is essentially planar, with a maximum deviation of -0.021?(1)?Å. The ?-lactam ring makes dihedral angles of 18.815?(9), 83.33?(7) and 53.62?(8)° with the mean planes of the benzene, xanthene and anthracene ring systems, respectively. The structure is stabilized by C-H??, C-H?N and C-H?O inter-actions.

Project description:The title chalcone derivative, C(24)H(18)O(2), which consists of the substituted 4-methoxy-phenyl and anthracene rings bridged by the prop-2-en-1-one unit, exists in a cis configuration.
