4-Nitro-N-(4-nitro-benzo-yl)benzamide.

ABSTRACT: The central acetyl-acetamide moiety in the title compound, C(14)H(9)N(3)O(6), is buckled [e.g. the C-N-C-O torsion angle is 14.3?(6)°] but the r.m.s. deviation for the five atoms is 0.044?Å. The benzene rings lie on the same side of the central plane, forming dihedral angles of 37.17?(15) and 28.58?(19)° with it. The dihedral angle between the two rings is 17.8?(2)° indicating that the mol-ecule is curved. The carbonyl groups are syn to each other and anti to the amino H atom. This allows for the formation of N-H?O hydrogen bonds in the crystal, which leads to twisted chains along the b axis. Positional disorder (50:50) of the O atoms was modelled for both the nitro groups.

4-Nitro-N-(3-nitro-phen-yl)benzamide.

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.

N-(2-Nitro-phen-yl)benzamide.

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.

N-[(Morpholin-4-yl)carbonothio-yl]-4-nitro-benzamide.

Project description:In the title compound, C(12)H(13)N(3)O(4)S, the nitro group is slightly twisted [6.58?(11)°] from the benzene ring plane. The morpholine ring adopts a chair form.

C-H?O and C-H?S inter-actions are also observed.

In the crystal, an inter-molecular N-H?O hydrogen bond, which forms an infinite polymeric chain along the c axis, and weak C-H?O and C-H?S hydrogen bonds are observed.
