Four mol-ecular salts made from hexa-methyl-ene-tetra-minium and 2-chloro-4-nitro-benzoate have been synthesized and are reported, namely ammonium hexa-methyl-ene-tetra-minium bis-(2-chloro-4-nitro-benzoate), NH4+·C6H13N4+·2C7H3ClNO4-, (I), hexa-methyl-ene-tetra-minium hydrogen bis-(2-chloro-4-nitro-benzoate), 0.5C6H13N4+·C7H3.50ClNO4-, (II), hexa-methyl-ene-tetra-minium 2-chloro-4-nitro-benzoa...

In the title compound, C(15)H(11)ClO(3), the dihedral angle between the aromatic rings is 84.29 (8)°. In the crystal, mol-ecules are linked by weak C-H⋯π inter-actions.

The title compound, C(13)H(11)NO(3)S, was synthesized from methyl anthranilate, triethyl-amine and 2-thio-phenoyl chloride in benzene. The mol-ecular conformation is stabilized by an intra-molecular N-H⋯O hydrogen bond. The dihedral angle between the rings is 2.74 (12)°. In the crystal, C-H⋯O inter-actions link neighbouring mol-ecules into a three-dimensional network.

In the mol-ecule of the title compound, C15H12ClNO3, the chloro-benzamide and benzoate units are almost co-planar, with a dihedral angle between the six-membered rings of 2.99 (10)°. An intra-molecular N-H⋯O hydrogen bond occurs. In the crystal, each mol-ecule is linked to a symmetry-equivalent counterpart across a twofold rotation axis by weak C-H⋯O and C-H⋯Cl hydrogen bonds, forming dimers. T...

In the title compound, C15H11BrO3, the dihedral angle between the benzene rings is 72.59 (6)°. In the crystal, pairs of C-H⋯π contacts form inversion dimers. Additional C-H⋯O hydrogen bonds generate R2(1)(6) ring motifs and stack these dimers along the b axis. Short inter-molecular Br⋯O contacts of 3.254 (3) Å are also observed and link the stacks into a three-dimensional network.

The title compound, C(15)H(15)NO(4)S, was prepared by simple condensation of methyl 2-amino-benzoate and 4-methyl-benzene-sulfonyl chloride. The dihedral angle between the benzene rings is 84.36 (6)°. The mol-ecular structure is stabilized by an intra-molecular N-H⋯O hydrogen-bonding inter-action involving the carbonyl group as acceptor, generating an S(6) graph-set motif.

Benzoate catabolism is thought to play a key role in aerobic bacterial degradation of biphenyl and polychlorinated biphenyls (PCBs). Benzoate catabolic genes were cloned from a PCB degrader, Rhodococcus sp. strain RHA1, by using PCR amplification and temporal temperature gradient electrophoresis separation. A nucleotide sequence determination revealed that the deduced amino acid sequences encod...
