Project description:In the title mol-ecule, C(12)H(11)NO(4), the two acetyl groups are inclined by 71.3?(1) and 46.2?(1)° to the benzene ring. In the crystal structure, mol-ecules are linked into a chain along the c axis by C-H?O hydrogen bonds.

Project description:In the mol-ecule of the title compound, C(14)H(10)N(2)O(4), the dihedral angle formed by the benzene rings is 53.66?(5)°. In the crystal structure, mol-ecules are linked into chains parallel to the [01] direction by inter-molecular C-H?O hydrogen-bonding inter-actions.

Project description:The title compound, C(13)H(9)N(3)O(5), prepared as a solid derivative of 3-nitro-analine via reaction with 4-nitro-benzoyl chloride, crystallizes in a chiral space group. The mol-ecule is non-planar with a dihedral angle of 26.1?(1)° between the two benzene rings. Both nitro groups are twisted slightly out of the plane of their corresponding benzene rings, making dihedral angles of 10.7?(4) and 13.5?(4)°. The mol-ecules are stacked along the a axis with benzene ring centroid-centroid distances of 3.8878?(6)?Å. In the crystal, inter-molecular benzene C-H?O inter-actions involving one nitro group and the carbonyl group link the mol-ecules, forming chains along [001]. An additional set of aromatic C-H?O inter-actions with the second nitro group form chains along [101], connecting adjacent chains to create layers perpendicular to the b axis.

Project description:In the title compound, C(13)H(10)FN(3)O(3), the dihedral angle between the fluoro-phenyl and nitro-phenyl ring planes is 6.51?(9)°. The crystal structure features N-H?O hydrogen bonds.

Project description:In the title compound, C(13)H(10)ClN(3)O(3), prepared by the reaction of 1-chloro-3-isocyanato-benzene with 4-nitro-benzenamine, the two substituent benzene rings are roughly coplanar [inter-ring dihedral angle = 8.70?(7)°]. In the crystal, mol-ecules make cyclic inter-molecular associations through two urea-nitro N-H?O hydrogen bonds, forming a chain structure [give chain direction] in which there are also weak inter-molecular C-H?Cl inter-actions. The urea O atom has only intra-molecular aromatic ring C-H?O associations.

Project description:In the title compound, C(19)H(16)NO(4)P, the dihedral angle between the mean planes of the phenyl rings bonded to the P atom is 75.4 (1)°. In the crystal, mol-ecules are linked into chains running along the a axis by inter-molecular O-H⋯O hydrogen bonds. Mol-ecules are further connected into a three-dimensional array by weak C-H⋯O hydrogen bonds.

Project description:In the title compound, C(13)H(10)N(2)O(3), the central C-C(=O)-N-C amide unit makes dihedral angles of 21.68?(4) and 19.08?(4)°, respectively, with the phenyl and nitro-benzene rings. The two aromatic rings are inclined at 3.74?(3)° and the nitro group is skewed out of the attached benzene ring plane by 18.55?(8)°. An intra-molecular N-H?O inter-action to an O atom of the nitro substituent generates an S(6) ring motif. In the crystal, C-H?O contacts generate two centrosymmetric ring systems with R(2) (2)(14) and R(2) (2)(20) graph-set motifs, forming zigzag chains down the a axis. ?-? inter-actions between adjacent phenyl and nitro-benzene rings [centroid-centroid distance = 3.6849?(6)?Å] also form centrosymmetric dimers. These and an additional C-H?O hydrogen bond generate an extensive three-dimensional network structure.

Project description:The asymmetric unit of the title compound, C(12)H(8)N(2)O(6)S, an important diphenyl sulfone derivative, contains one half-mol-ecule; a mirror plane passes through the SO(2) group. The dihedral angle between the two symmetry-related benzene rings is 40.10?(13)°. An intra-molecular C-H?O hydrogen bond results in the formation of a five-membered ring, which adopts an envelope conformation.

Project description:In the title compound, C8H9N3O3, the dihedral angle between the benzene ring and the acetohydrazide C-C(=O)-N-N plane [maximum deviation = 0.0471?(13)?Å] is 87.62?(8)°. The nitro group is twisted by 19.3?(2)° with respect to the benzene ring. In the crystal, N-H?O hydrogen bonds link the mol-ecules into a double-column structure along the b axis.

Project description:In the title compound, C13H10N2O4, the nitro groups are twisted significantly relative to the benzene rings [dihedral angles = 16.64?(18) and 28.02?(11)°]. The benzene groups are nearly perpendicular to each other [dihedral angle = 87.72?(6)°]. Short inter-molecular N?O and C?O [2.981?(2) and 3.060?(2)?Å, respectively] contacts suggest possible weak ?-inter-actions between nitro groups and between benzene and nitro groups. In addition, there are ?-? inter-actions between one benzene group and an inversion-related equivalent [inter-planar separation = 3.494?(2)?Å].
