2-Methyl-3-(4-nitrophenyl)acrylic acid
The title compound, C(10)H(9)NO(4), forms R(2) (2)(8) dimers due to inter-molecular O-H⋯O hydrogen bonding in the crystal structure. Two dimers are further linked to each other through two inter-molecular C-H⋯O hydrogen bonds, forming an R(3) (3)(7) ring motif. The nitro groups form an intra-molecular C-H⋯O hydrogen bond mimicking a five-membered ring. As a result of these hydrogen bonds, polym...
متن کاملRemoval of 2,4-dichlorophenoxyacetic acid and 4-chloro-2-methyl phenoxyacetic acid herbicides from aquatic environments by a novel polymer magnetic nanoparticles
Background and Objective: Increased use of pesticides and chemical fertilizers in agriculture in order to increase the productivity of fertile lands has led to pollution of water resources with a variety of pollutants, including herbicides. In this study, a new polymer magnetic nanoadsorbent named PV/S-g-3D-GO/N was synthesized and used to remove 2,4-D and MCPA herbicides from aquatic environme...
متن کامل2-Chloro-4-(2-iodobenzenesulfonamido)benzoic acid
In the title compound, C(13)H(9)ClINO(4)S, the dihedral angle between the aromatic rings is 81.04 (17)°. The disposition of the I and Cl atoms attached to the two rings is anti. In the crystal, mol-ecules are connected via O-H⋯O and N-H⋯O hydrogen bonds.
متن کامل3-[2-Chloro-4-(trifluoromethyl)phenoxy]benzoic acid
The asymmetric unit of the title compound, C(14)H(8)ClF(3)O(3), comprises two independent mol-ecules. The rings in each molecule are connected together via O-H⋯O hydrogen bonds to form classical hydrogen-bonded carb-oxy-lic acid dimers. The dihedral angles between the benzene rings are 80.7 (1) and 68.7 (1)°.
متن کاملMethyl 6-chloro-2-methyl-4-phenylquinoline-3-carboxylate
In the title compound, C(18)H(14)ClNO(2), the quinoline ring system is planar (r.m.s. deviation = 0.032 Å) and the phenyl ring is twisted away from it by 57.5 (1)°. The crystal structure is stabilized by weak C-H⋯π inter-actions.
