    1-(Morpholin-4-yl)-4-(2-nitro-phen-yl)spiro-[azetidine-3,9'-xanthen]-2-one
    (2014) Atioğlu, Zeliha; Akkurt, Mehmet; Jarrahpour, Aliasghar; Heiran, Roghayeh; Özdemir, Namık
    In the title compound, C22H21N3O5, the ?-lactam (azetidin-2-one) ring is nearly planar [maximum deviation = 0.010 (1) Å] and makes dihedral angles of 69.22 (5), 55.32 (5) and 89.42 (4)° with the least-squares planes formed by the four C atoms of the morpholine ring, which adopts a chair conformation, the benzene ring and the xanthene ring system, respectively. In the crystal, C-H?O hydrogen-bond contacts connect neighbouring mol-ecules into infinite zigzag chains running parallel to the b axis.

    1-[3-(Morpholin-4-yl)prop-yl]-3-[(naph-tha-len-2-yl)oxy]-4-(3-nitro-phen-yl)azeti-din-2-one
    (2014) Atioğlu, Zeliha; Akkurt, Mehmet; Jarrahpour, Aliasghar; Heiran, Roghayeh; Özdemir, Namık
    In the title compound, C26H27N3O5, the ?-lactam (azetidin-2-one) ring is nearly planar [maximum deviation = 0.011?(3)?Å]. The mean plane formed by the four C atoms of the morpholine ring, which adopts a chair conformation, the benzene ring and the naphthalene ring system form dihedral angles of 72.85?(17), 87.46?(15) and 65.96?(11)°, respectively, with the ?-lactam ring. In the crystal, molecules are linked via C—H?O hydrogen bonds, forming inversion dimers with R 2 2(8).

    3-(2,4-Di-chloro-phen-oxy)-1-(4-meth-oxy-benz-yl)-4-(4-nitro-phen-yl)azetidin-2-one
    (2014) Atioğlu, Zeliha; Akkurt, Mehmet; Jarrahpour, Aliasghar; Heiran, Roghayeh; Özdemir, Namık
    The ?-lactam ring of the title compound, C23H18Cl2N2O5, is nearly planar [maximum deviation = 0.019?(2)?Å for the N atom] and its mean plane makes dihedral angles of 56.86?(15), 68.83?(15) and 83.75?(15)° with the di­chloro-, nitro- and meth­oxy-substituted benzene rings, respectively. In the crystal, mol­ecules are linked by pairs of C—H?O hydrogen bonds, forming inversion dimers with R 2 2(10) loops. The dimers are linked by further C—H?O hydrogen bonds, forming sheets lying parallel to (001). The mol­ecular packing is further stabilized by C—H?? inter­actions.

    (E)-4-{[(Morpholin-4-yl)imino]-meth-yl}benzo-nitrile
    (2014) Atioğlu, Zeliha; Akkurt, Mehmet; Jarrahpour, Aliasghar; Heiran, Roghayeh; Özdemir, Namık
    In the title compound, C12H13N3O, the morpholine ring adopts a chair conformation and its mean plane is inclined to that of the benzene ring by 16.78?(12)°. The N—N=C—C bridge, which has an E conformation, has a torsion angle of 173.80?(19)°. In the crystal, mol­ecules stack along the a axis but there are no significant inter­molecular inter­actions present.
