2-Chloro-N-(4-meth-oxy-phen-yl)benzamide.

Project description:In the title compound, C(14)H(12)ClNO(2), the chloro- and meth-oxy-substituted benzene rings are close to orthogonal [dihedral angle = 79.20?(3)°]. These rings also make angles of 45.9?(3) and 33.5?(3)° with the amide -CONH- unit. The meth-oxy substituent lies close to the meth-oxy-benzene ring plane, with a maximum deviation of 0.142?(3)?Å for the methyl C atom. The N-H bond is anti to the 2-chloro substituent of the aniline ring. In the crystal structure, inter-molecular N-H?O hydrogen bonds form C(4) chains augmented by a weak C-H?O inter-action involving an ortho H atom of the meth-oxy benzene ring that generates an R(2) (1)(6) motif. The chains stack the mol-ecules into columns down the b axis. Adjacent columns are linked by additional C-H?O and C-H?? contacts, generating a three-dimensional network.

N-[(2-Chloro-phen-yl)sulfon-yl]-2-meth-oxy-benzamide.

Project description:The title compound, C14H12ClNO4S, crystallizes with two mol-ecules in the asymmetric unit. The dihedral angles between the benzene rings are 89.68?(1) (mol-ecule 1) and 82.9?(1)° (mol-ecule 2). In each mol-ecule, intra-molecular N-H?O hydrogen bonds between the amide H atom and the meth-oxy O atom generate S(6) loops. In the crystal, mol-ecule 2 is linked into inversion dimers through pairs of C-H?O inter-actions, forming an R 2 (2)(8) ring motif. Mol-ecules 1 and 2 are further linked along the b-axis direction through C-H?? inter-actions. The crystal structure is further stabilized by several ?-? stacking inter-actions [centroid-centroid separations = 3.7793?(1), 3.6697?(1) and 3.6958?(1)?Å], thus generating a three-dimensional architecture.

N-(4-Chloro-phen-yl)-4-meth-oxy-3-(propanamido)-benzamide cyclo-hexane hemisolvate.

Project description:The title compound, C(17)H(17)ClN(2)O(3)·0.5C(6)H(12), was prepared by the condensation reaction of 4-meth-oxy-3-(propanamido)-benzoic acid with 4-chloro-aniline. The Cl atom, the propionyl CH(3) group and the cyclo-hexyl CH(2) group are disordered over two sets of sites of equal occupancy in both mol-ecules. The cyclo-hexane solvent mol-ecule is disordered over two orientations which were modelled with relative occupancies of 0.484 (4) and 0.516 (4). In the crystal, there are a number of N-H⋯O hydrogen bonds, forming layers perpendicular to (001).

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

Project description:In the title compound, C(15)H(14)N(2)O(5), the central amide C-C(=O)-N-C unit forms dihedral angles of 28.17?(13) and 26.47?(13)° with the two benzene rings, whereas the two benzene rings are almost coplanar, making a dihedral angle of 4.52?(13)°. The two meth-oxy and the nitro substituents are almost coplanar with their attached benzene rings, with C-O-C-C torsion angles of -1.3?(4) and -4.6?(4)°, and an O-N-C-C torsion angle of 17.1?(3)°. In the crystal, mol-ecules are linked via C-H?O and N-H?O inter-actions, forming a tape running along the b axis.

Crystal structure of N-{4-[(6-chloro-pyridin-3-yl)meth-oxy]phen-yl}-2,6-di-fluoro-benzamide.

Project description:In the title compound, C19H13ClF2N2O2, the conformation of the N-H bond in the amide segment is anti to the C=O bond. The mol-ecule is not planar, with dihedral angles between the central benzene ring and the outer benzene and pyridyl rings of 73.35?(7) and 81.26?(6)°, respectively. A weak intra-molecular C-H?O hydrogen bond occurs. In the crystal, N-H?N, C-H?O and C-H?F hydrogen bonds lead to the formation of dimers. The N-H?N inversion dimers are linked by ?-? contacts between adjacent pyridine rings [centroid-centroid = 3.8541?(12)?Å] and C-H?? inter-actions. These contacts combine to stack the mol-ecules along the a axis.

N-[2-({[1-(4-Chloro-phen-yl)-1H-pyrazol-3-yl]-oxy}meth-yl)phen-yl]-N-meth-oxy-hydrazinecarboxamide.

Project description:In the title compound, C(18)H(18)ClN(5)O(3), the hydrazinecarboxamide N-N-C(O)-N unit is nearly planar [maximum deviation = 0.074?(2)?Å] and is inclined at a dihedral angle of 57.43?(7)° with respect to the plane of the attached benzene ring. The chloro-phenyl group makes dihedral angles of 19.71?(7) and 34.07?(6)° with the pyrazole and benzene rings, respectively. In the crystal, pairs of N-H?O hydrogen bonds link the mol-ecules into inversion dimers that are further linked into chains along the a-axis direction by N-H?N hydrogen bonds. In addition, ?-? stacking inter-actions are observed between benzene rings [centroid-centroid distance = 3.680?(1)?Å].

3-Chloro-N-(4-meth-oxy-phen-yl)propanamide.

Project description:The title compound, C(10)H(12)ClNO(2), is a halogenated derivative of a secondary amide bearing an aromatic substituent. The C(=O)-N(H)-C(ar)-C(ar) torsion angle of -33.70 (18)° rules out the presence of resonance spanning the amide as well as the aromatic system. In the crystal, classical N-H⋯O hydrogen bonds, as well as C-H⋯O contacts connect the mol-ecules into chains propagating along the a axis.

Project description:In the title compound, C(21)H(12)ClN(3)O, the phenoxy ring makes dihedral angles of 51.42 (5) and 65.01 (6)°, respectively, with the chlorophenyl and phthalonitrile rings. In the crystal structure, the mol-ecules are inter-linked through weak C-H⋯N and C-H⋯π contacts, and π-π stacking inter-actions via crystallographic inversion centres form a three-dimensional network. The distance between the centroids of the phthalonitrile rings is 3.9104 (11)Å, with a slippage between the rings of 1.626 Å and a perpendicular distance between the rings of 3.556 Å.

2-{[3-Chloro-4-(4-chloro-phen-oxy)phen-yl]imino-meth-yl}-4-nitro-phenol.

Project description:In the title compound, C19H12Cl2N2O4, the imine bond length of 1.257 (6) Å is typical of a double bond. The dihedral angle between the para-nitro benzene ring and the central benzene ring is 12.06 (3)° and that between the central benzene and the para-chloro benzene ring is 73.81 (2)°. An intra-molecular O-H⋯N hydrogen bond generates an S(6) ring motif. In the crystal, mol-ecules are linked together by two pairs of C-H⋯O interactions (to the same O atom acceptor), forming inversion dimers. A short Cl⋯Cl contact [3.232 (4) Å] is observed.
