ABSTRACT: In the title compound, C(13)H(9)ClN(2)O(4), the dihedral angle between the benzene rings is 79.5 (1)°. The mean plane of the carbamate group makes angles of 7.4 (2) and 73.6 (2)° with the mean planes of the two benzene rings. In the crystal, weak C-H⋯O inter-actions are observed between the mol-ecules, connecting them into a two-dimensional network.

Crystal structures of 4-chloro-phenyl N-(3,5-di-nitro-phen-yl)carbamate and phenyl N-(3,5-di-nitro-phen-yl)carbamate.

Project description:The title compounds, C13H8ClN3O6, (I), and C13H9N3O6, (II), differ in the orientation of the two aromatic rings. In (I), they are essentially coplanar, making a dihedral angle of 8.2 (1)°, while in (II), they are inclined to one another by 76.2 (1)°. The two nitro groups are essentially coplanar with the attached benzene rings, as indicated by the dihedral angles of 1.4 (2) and 2.3 (2)° in (I), and 4.96 (18) and 5.4 (2)° in (II). The carbamate group is twisted slightly from the attached benzene ring, with a C-N-C-O torsion angle of -170.17 (15)° for (I) and 168.91 (13)° for (II). In the crystals of of both compounds, mol-ecules are linked via N-H⋯O hydrogen bonds, forming chains propagating along [010]. In (I), C-H⋯O hydrogen bonds also link mol-ecules within the chains. The crystal packing in (I) also features a very weak π-π inter-action [centroid-centroid distance = 3.7519 (9) Å].

4-Nitro-phenyl N-phenyl-carbamate.

Project description:The title compound, C(13)H(10)N(2)O(4), was synthesized as an inter-mediate for the preparation of ureas. The two aromatic rings are twisted about the central carbamate group with a C-C-N-C torsion angle of 139.6 (2)° and a C-C-O-C torsion angle of 95.9 (2)°. The mol-ecules are linked into one-dimensional chains by N-H⋯O hydrogen bonds along the b axis. Weak inter-actions between O atoms of the nitro groups (O⋯O = 3.012 Å) connect two adjacent chains.

Project description:In the title mol-ecule, C13H11N3O6S, the dihedral angle between the benzene rings is 35.52 (8)°. An intra-molecular N-H⋯O hydrogen bond forms an S(6) ring. In the crystal, mol-ecules are linked via N-H⋯O hydrogen bonds into chains along [101] incorporating R2(2)(8) and R2(2)(16) rings.

2-Amino-5-nitro-phenyl 2-chloro-phenyl ketone.

Project description:In the title compound, C(13)H(9)ClN(2)O(3), an intra-molecular hydrogen bond between the carbonyl O and an amine H atom from the 2-amino-benzoyl group stabilizes the mol-ecule, keeping these two groups nearly in the same plane [dihedral angle 14.6 (6)°]. The dihedral angle between the mean planes of the planar 2-amino-benzoyl and 2-chloro-benzoyl groups is 73.8 (6)°. The crystal packing is stabilized by a collection of inter-mediate hydrogen-bonding inter-actions which forms an infinite N-H⋯O⋯H-N-H⋯O hydrogen-bonded chain along the c axis in concert with weak N-H⋯Cl inter-actions in the same direction, producing a two-dimensional inter-molecular bonding network parallel to (001). Additional weak C-Cl⋯Cg [Cl⋯Cg = 3.858 (3) Å] and N-O⋯Cg [O⋯Cg = 3.574 (1) and 3.868 (6) Å] π-ring inter-actions provide added support to the crystal stability. A MOPAC computational calculation gives support to these observations.

Crystal structure of phenyl N-(4-nitro-phen-yl)carbamate.

Project description:The asymmetric unit of the title compound, C13H10N2O4, contains two independent mol-ecules (A and B). The dihedral angle between the aromatic rings is 48.18 (14)° in mol-ecule A and 45.81 (14)° in mol-ecule B.
