N-[4-Cyano-3-(trifluoro-meth-yl)phen-yl]-2-eth-oxy-benzamide.

ABSTRACT: In the title compound, C(17)H(13)F(3)N(2)O(2), the two aromatic rings are essentially coplanar, forming a dihedral angle of 2.78?(12)°. The non-H atoms of the eth-oxy group are coplanar with the attached ring [maximum deviation = 0.271?(3)?Å]. An intra-molecular N-H?O hydrogen bond occurs. In the crystal structure, mol-ecules are linked by inter-molecular C-H?N and C-H?F hydrogen bonds.

2-[4-(Trifluoro-meth-oxy)phen-yl]-1H-benzimidazole.

Project description:In the title compound, C(14)H(9)F(3)N(2)O, the best planes of the benzimidazole group and benzene ring form a dihedral angle of 26.68 (3)°. In the crystal, N-H⋯N hydrogen bonds link the mol-ecules into infinite chains parallel to the c axis. Stacking inter-actions between the benzimidazole groups [centroid-centroid distance = 3.594 (5) Å] assemble the mol-ecules into layers parallel to (100). The trifluoro-methyl group is disordered over three sets of sites with site-occupancy factors of 0.787 (4), 0.107 (7) and 0.106 (7).

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.

Project description:In the title mol-ecule, C(21)H(19)N(3)O(2), the central pyridine ring makes dihedral angles of 14.46 (9) and 34.67 (8)° with the 4-amino- and 4-eth-oxy-substituted benzene rings, respectively.

In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds into chains along [201]. Weak C-H⋯O hydrogen bonds and C-H⋯π inter-actions are also present.
