2-(4-Bromo-phen-yl)-N-(5-methyl-pyridin-2-yl)acetamide.

ABSTRACT: The asymmetric unit of the title compound, C(14)H(13)BrN(2)O, consists of two mol-ecules; the dihedral angles between the pyridine and benzene rings are 87.99 (9) and 84.28 (9)°. An intra-molecular C-H⋯O hydrogen bond generates an S(6) ring in each mol-ecule. In the crystal, mol-ecules are linked via N-H⋯N and C-H⋯O hydrogen bonds into a three-dimensional network. The crystal structure also features weak π-π stacking inter-actrions between the benzene rings [centroid-to-centroid distance = 3.6829 (12) Å].

N-(5-Bromo-pyridin-2-yl)acetamide.

Project description:The asymmetric unit of the title compound, C(7)H(7)BrN(2)O, contains two mol-ecules, in one of which the methyl H atoms are disorderd over two orientations in a 0.57?(3):0.43?(3) ratio. The dihedral angles between the pyridine rings and the acetamide groups are 7.27?(11) and 8.46?(11)°. In the crystal, mol-ecules are linked by N-H?O and C-H?O hydrogen bonds generating bifurcated R(2) (1)(5) ring motifs, which in turn lead to [110] chains.

N-(3-Bromo-phen-yl)acetamide.

Project description:The conformation of the N-H bond in the structure of the title compound, C(8)H(8)BrNO, is anti to the C=O bond and to the meta-bromo substituent of the aromatic ring in both independent mol-ecules comprising the asymmetric unit. Mol-ecules are linked through N-H?O hydrogen bonding into supra-molecular chains with a twisted topology.

N-(4-Bromo-phen-yl)-2-(4-chloro-phen-yl)acetamide.

Project description:The title compound, C(14)H(11)BrClNO, consists of chloro-benzene and bromo-benzene units which are linked at either end of the N-methyl-propionamide group. The chloro-benzene unit [maximum deviation = 0.005?(4)?Å] makes a dihedral angle of 68.21?(19)° with the bromo-benzene unit [maximum deviation = 0.012?(3)?Å]. In the crystal, N-H?O hydrogen bonds link the mol-ecules into chains along [010].

2-(4-Bromo-phen-yl)-N-(2,6-dimethyl-phen-yl)acetamide.

Project description:In the title compound, C(16)H(16)BrNO, the dihedral angle between the benzene rings is 69.8?(2)°. In the crystal, N-H?O hydrogen bonds link the mol-ecules into C(4) chains propagating in [100]. Adjacent mol-ecules in the chains are also linked by C-H?O inter-actions which, along with the N-H?O hydrogen bonds, generate R(2) (1)(6) loops.

2-(4-Bromo-phen-yl)-N-(3,4-di-fluoro-phen-yl)acetamide.

Project description:In the title compound, C14H10BrF2NO, the dihedral angle between the mean planes of the 4-bromo-phenyl and 3,4-di-fluoro-phenyl rings is 66.4?(1)°. These two planes are twisted by 40.0?(5) and 86.3?(2)°, respectively, from that of the acetamide group. In the crystal, N-H?O hydrogen bonds and weak C-H?O and C-H?F inter-actions form infinite chains along [100].

2-Bromo-N-(2-chloro-phen-yl)acetamide.

Project description:The conformation of the N-H bond in the structure of the title compound, C(8)H(7)BrClNO, is syn to the 2-chloro substituent in the aniline ring and anti to both the C=O and C-Br bonds in the side chain, similar to that observed in 2-chloro-N-(2-chloro-phen-yl)acetamide. In the crystal, mol-ecules are linked into chains along the a axis by N-H?O hydrogen bonds. These chains are in turn linked into pairs, in the form of columns, through much weaker C-H?Cl and Br?Br [4.3027?(3)?Å] inter-actions.

N-(2-Bromo-4-methyl-phen-yl)-2-(5-methyl-2-phenyl-pyrazolo-[1,5-a]pyrimidin-7-yl)acetamide.

Project description:The fused pyrazole and pyrimidine rings in the title compound, C22H19BrN4O, are almost coplanar, their planes being inclined to one another by 2.08 (13)°. The dihedral angles formed by the mean plane of the fused ring system and the phenyl and benzene rings are 16.21 (4) and 82.84 (4)°, respectively. An intra-molecular N-H⋯N hydrogen bond is observed. In the crystal, mol-ecules form inversion dimers via pairs of C-H⋯O hydrogen bonds. π-π inter-actions, with centroid-centroid distances of 3.4916 (9) Å, connect the dimers into a three-dimensional network.

N-{4-[(4-Methyl-phen-yl)sulfamo-yl]phen-yl}acetamide.

Project description:The title mol-ecule, C(15)H(16)N(2)O(3)S, has a twisted U-shaped conformation. The twist occurs in the central C-S(=O)(2)N(H)-C unit with the C-S-N-C torsion angle being -58.38?(14)°. The benzene rings lie to the same side of the mol-ecule and form a dihedral angle of 67.03?(10)°. The crystal packing features N-H?O hydrogen bonding, which leads to supra-molecular chains with a tubular topology along the b axis. Intra-molecular C-H?O inter-actions are also observed.

N-(4-Bromo-phen-yl)-2-(2-thien-yl)acetamide.

Project description:The thienyl ring in the title compound, C(12)H(10)BrNOS, is disordered over two diagonally opposite positions, the major component having a site-occupancy factor of 0.660?(5).

Linear supra-molecular chains along the a axis are found in the crystal structure through the agency of N-H?O hydrogen bonding.
