N-[4-(4-Nitro-phen-oxy)phen-yl]acetamide.

ABSTRACT: The asymmetric unit of the title compound, C(14)H(12)N(2)O(4), contains two mol-ecules that differ principally in the orientation of the acetamide substituent to the adjacent benzene ring with dihedral angles of 44.77 (7) and 19.06 (7)°. The dihedral angles between the benzene rings are 64.46 (4) and 80.84 (4)°. In the crystal, classical N-H⋯O hydrogen bonds form C(4) chains along [100]. These chains are inter-linked by C-H⋯O contacts forming R(2) (2)(10) rings. In the crystal, π-π inter-actions are observed with a distance of 3.5976 (18) Å between the centroids of the nitro-substituted benzene rings of one type of mol-ecule.

N-[(2-Hydr-oxy-5-methoxy-phen-yl)(3-nitro-phen-yl)meth-yl]acetamide.

Project description:In the title compound, C(16)H(16)N(2)O(5), the meth-oxy group is disordered with site occupancies of 0.20 (3) and 0.80 (3). The dihedral angle between the two aromatic rings is 73.7 (2)°. The crystal structure is characterized by intermolecular N-H⋯O, O-H⋯O, C-H⋯O and C-H⋯π hydrogen bonds.

N-Benzyl-2-(2-bromo-phen-yl)-2-(2-nitro-phen-oxy)acetamide.

Project description:The title compound, C(21)H(17)BrN(2)O(4), a 2-phen-oxy-2-phenyl-acetamide derivative, exhibits a stereogenic center but crystallizes as a racemate as indicated by the centrosymmetric space group. In the mol-ecular structure, the nitro-substituted benzene ring is coplanar [dihedral angle = 12.9?(1)°] with the plane formed by H-N-C(=O)-C=O due to intra-molecular N-H?O hydrogen-bond inter-actions.

N-(4-Meth-oxy-2-nitro-phen-yl)acetamide.

Project description:In the title compound, C9H10N2O4, the three substituents vary in the degree of lack of planarity with the central phenyl ring. The meth-oxy group is nearest to being coplanar, with a C-C-O-C torsion angle of 6.1 (5)°. The nitro group is less coplanar, with a 12.8 (5)° twist about the C-N bond and the acetamido group is considerably less coplanar with the central ring, having a 25.4 (5)° twist about the C-N bond to the ring. The NH group forms an intra-molecular N-H⋯O hydrogen bond to a nitro-group O atom.

N-(4-Meth-oxy-3-nitro-phen-yl)acetamide.

Project description:The title compound, C9H10N2O4, crystallizes with a disordered nitro group in twinned crystals. Both the meth-oxy group and the acetamide groups are nearly coplanar with the phenyl ring, and the C-N-C-O torsion angle [0.2 (4)°] is also insignificantly different from zero. Overall, the 12-atom meth-oxy-phenyl-acetamide group is nearly planar, with an r.m.s. deviation of 0.042 Å. The nitro group is twisted out of this plane by about 30°, disordered into two orientations with opposite senses of twist. In the crystal, the N-H group donates a hydrogen bond to a nitro oxygen atom, generating chains propagating in the [101] direction. The amide carbonyl oxygen atom is not involved in the hydrogen bonding.

N-(4-Meth-oxy-2-nitro-phen-yl)-N-(methyl-sulfon-yl)acetamide.

Project description:In the title compound, C(10)H(12)N(2)O(6)S, the nitro group is twisted slightly out of the plane of the aromatic ring, forming a dihedral angle of 20.79 (1)°. In the crystal, the mol-ecules arrange themselves as a chain along the a axis through inter-molecular C-H⋯O inter-actions.

N-(4-Eth-oxy-2,5-di-nitro-phen-yl)acetamide.

Project description:In the title compound, C10H11N3O6, the torsion angles about the bonds to the benzene ring are less than 4°, except for the nitro groups, which are twisted out of the ring plane by 25.27 (3) and 43.63 (2)°. The N-H group forms a bifurcated hydrogen bond, with an intra-molecular component to a nitro group O atom and an inter-molecular component to the other nitro group, thereby forming chains propagating in the [010] direction. Several weak C-H⋯O inter-actions are also present.

N-{4-[(2-Meth-oxy-phen-yl)sulfamo-yl]phen-yl}acetamide.

Project description:In the title compound, C(15)H(16)N(2)O(4)S, the S atom has a distorted tetra-hedral geometry [maximum deviation: O-S-O = 118.25 (7)°]. The two aromatic rings make a dihedral angle of 62.67 (10)° with each other. An intra-molecular N-H⋯O hydrogen bond forms an S(6) ring motif. In the crystal, mol-ecules form centrosymmetric dimers via pairwise N-H⋯O inter-actions, forming an R(2) (2)(8) ring motif, and these dimers are connected by N-H⋯O hydrogen bonds, generating a three-dimensional network. Furthermore, a weak C-H⋯π inter-action helps to reinforce the crystal structure. The O atom in the acetamide group is disordered over two positions with major and minor occupancies of 0.52 (5) and 0.48 (5), respectively.

2,2-Dichloro-N-(3-nitro-phen-yl)acetamide.

Project description:The conformation of the N-H bond in the structure of the title compound (3NPDCA), C(8)H(6)Cl(2)N(2)O(3), is anti to the meta-nitro group, similar to that in the structures of 2-chloro-N-(3-nitro-phen-yl)acetamide (3NPCA) and 2,2,2-trichloro-N-(3-nitro-phen-yl)acetamide (3NPTCA), and the meta-chloro group in 2,2-dichloro-N-(3-chloro-phen-yl)acetamide (3CPDCA). The geometric parameters of 3NPDCA are similar to those of 2,2-dichloro-N-phenyl-acetamide, 3CPDCA, 3NPCA, 3NPTCA and other acetanilides. Inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into chains running along the b axis.

Project description:The title compound, C(11)H(11)NO(2), was synthesized by chemoselective N-acetyl-ation of 4-amino-phenol followed by reaction with propargyl bromide in the presence of K(2)CO(3). the acetamide and propyn-1-yloxy substituents form dihedral angles of 18.31?(6) and 7.01?(10)°, respectively, with the benzene ring. In the crystal, mol-ecules are linked by N-H?O hydrogen bonds into chains along [010]. C-H?O and C-H?? inter-actions also occur.

Project description:The title compound, C(15)H(14)N(2)O(4), is an important inter-mediate for the synthesis of thermotropic liquid crystals.

In addition, the crystal packing is stabilized by weak C-H⋯O hydrogen bonds.
