4-Bromobenzoyl 4-bromobenzoate monohydrate
In the title compound, C(14)H(8)Br(2)O(3)·H(2)O, the organic and water mol-ecules both have crystallographically imposed C(s) symmetry. The dihedral angle between the aromatic rings is 45.76 (11)°. In the crystal structure, inter-molecular C-H⋯O and O-H⋯O hydrogen bonds link the mol-ecules into chains parallel to the a axis. No π-π stacking inter-actions are observed in the crystal structure.
متن کامل(4-Chlorobenzoyl)(4-chlorophenyl)amino 3-(2-nitrophenyl)propanoate
In the title hydroxamic acid derivate, C22H16Cl2N2O5, the nitro-substituted benzene ring forms dihedral angles of 14.11 (15) and 16.08 (15)°, with the 4-chloro-benzoyl and 4-chloro-phenyl benzene rings, respectively. The dihedral angle between the chloro-substituted benzene rings is 2.28 (13)°. In the crystal, mol-ecules are linked by weak C-H⋯O hydrogen bonds, forming chains along [100].
متن کاملCharacterization of bacterial consortia capable of degrading 4-chlorobenzoate and 4-bromobenzoate under denitrifying conditions.
4-Chlorobenzoate and 4-bromobenzoate were readily degraded in denitrifying enrichment cultures established with river sediment, estuarine sediment or agricultural soil as inoculum. Stable denitrifying consortia were obtained and maintained by serial dilution and repeated feeding of substrates. Microbial community analyses were performed to characterize the 4-chlorobenzoate and 4-bromobenzoate d...
متن کاملIntramolecular electron transfer reactions in meso-(4-nitrophenyl)-substituted subporphyrins.
A2B-type meso-(4-nitrophenyl)-substituted subporphyrins have been synthesized and shown to undergo very fast photoinduced intramolecular charge separation (CS) and charge recombination (CR) between the subporphyrin core and the meso-4-nitrophenyl group in CH2Cl2 as probed by femtosecond time-resolved transient absorption spectroscopy. Red-shifted emissions were detected from charge-separated st...
متن کاملCrystal structure of 4,5-bis(4-dimethylaminophenyl)-2-(4-nitrophenyl)imidazole.
A nonlinear optical chromophore, 4,5-bis(4-dimethylaminophenyl)-2-(4-nitrophenyl)imidazole, was investigated by X-ray crystallography. The study focused on coplanarity among several aromatic rings, including phenyls and imidazole. Two phenyl rings with NMe2 groups are twisted by 46.39(3) degrees from each other. However, they are twisted by 23.05(5) degrees and 46.84(3) degrees from the imidazo...
