    Crystal structure of 2-[(3S, 4S)-4-(anthracen-9-yl)-1-(4-methoxyphenyl)-2-oxoazetidin-3-yl]-2-aza-2H-phenalene-1,3-dione unknown solvate

    The central beta-lactam ring of the title compound, C36H24N2O4, is almost planar (r.m.s. deviation = 0.003 angstrom) and makes dihedral angles of 17.17 (19), 89.76 (17) and 78.44 (17)degrees with the benzene ring, the anthracene ring (r.m.s. deviation = 0.003 angstrom) and the 1H-benzo[de] isoquinoline-1,3(2H)-dione moiety, which is nearly planar [maximum deviation = 0.098 (2) angstrom], respectively. The molecular structure is stabilized by an intramolecular C-H center dot center dot center dot N hydrogen bond. In the crystal, molecules are linked via C-H center dot center dot center dot pi and pi-pi stacking interactions [centroid-centroid distances = 3.5270 (19) and 3.779 (2) angstrom], forming a three-dimensional structure. A region of disordered electron density, probably disordered solvent molecules, was treated with the SQUEEZE procedure in PLATON [Spek (2015). Acta Cryst. C71, 9-18], which indicated a solvent cavity of 322 angstrom(3) containing approximately 91 electrons. Their formula mass and unit-cell characteristics were not taken into account during the refinement.

    Crystal structure of 2-[4-(4-chlorophenyl)-1-(4-methoxyphenyl)-2-oxoazetidin-3-yl]benzo[de]isoquinoline-1,3-dione dimethyl sulfoxide monosolvate
    (Int Union Crystallography, 2015) Celik, Ismail; Akkurt, Mehmet; Jarrahpour, Aliasghar; Rad, Javad Ameri; Celik, Omer
    In the title solvated compound, C28H19N2O4 center dot C2H6OS, the central beta-lactam ring is almost planar (r.m.s. deviation = 0.002 angstrom). It makes dihedral angles of 1.92 (11), 83.23 (12) and 74.90 (10)degrees with the methoxy-and chlorophenyl rings and the ring plane of the 1H-benzo[de]isoquinoline-1,3(2H)-dione group [maximum deviation = 0.089 (1)], respectively. An intramolecular C-H center dot center dot center dot O hydrogen bond closes an S(6) ring and helps to establish the near coplanarity of the beta-lactam and methoxybenzene rings. In the crystal, the components are linked by C-H center dot center dot center dot O hydrogen bonds, C-H center dot center dot center dot pi interactions and aromatic pi-pi stacking interactions [centroid-to-centroid distances = 3.6166 (10) and 3.7159 (10) angstrom], resulting in a three-dimensional network, The dimethyl sulfoxide solvent molecule is disordered over two sets of sites in a 0.847 (2):0.153 (2) ratio.
