In the title compound, C16H10ClNO2, the dihedral angle between the quinoline ring system and the benzene ring is 14.7 (5)°. The carboxylate group is twisted from the mean planes of the quinoline ring system and the benzene ring by 17.7 (5) and 32.1 (4)°, respectively. In the crystal, inversion dimers are formed with the molecules linked by pairs of weak C-H⋯O interactions arising from an activated aromatic C atom adjacent to the C-Cl bond, generating R 22(14) loops.

In the title compound, C18H15NO2, the dihedral angle between the mean planes of the quinoline ring system and the phenyl ring is 48.1 (5)°. The mean plane of the carboxylate group is twisted from the mean planes of the latter by 19.8 (8) and 64.9 (5)°, respectively. The crystal packing features weak C-H⋯O interactions, which form chains along [010]. Source

In the title compound, C17H12ClNO2, the dihedral angle between the mean planes of the quinoline ring system and the benzene ring is 68.7 (7)°. The mean plane of the carboxylate group is twisted from the latter planes by 14.0 (1) and 80.2 (4)°, respectively. In the crystal, weak C-H⋯O interactions are observed, forming chains along [001]. In addition, π-π stacking interactions [centroid-centroid distances = 3.8343 (13) and 3.7372 (13)Å] occur. No classical hydrogen bonds were observed. Source

Present study is an attempt to understand the hydrochemical characteristics of groundwater in Amol- Ghaemshahr region, Mazandaran province in North Iran. Groundwater samples were randomly collected from 77 wells in Amol-Ghaemshahr plain having different depths, varying from 2.4 m to 198 m. The physicochemical parameters such as pH, electrical conductivity (EC) and total dissolved solids (TDS) were measured in addition to major cation and anion concentrations. The abundance of major ions is as follows: Ca2+ > Na+ > Mg2+ > K+ and HCO3 - > Cl- >SO 4 2- > NO3 -. Thematic maps pertaining to pH, TDS, EC, Cl-, NO3 -, SO4 2- and Na + were presented in Geographical Information System (GIS) based maps. Different classes in thematic maps were categorized as desirable, permissible and unpermissible based on WHO standards for drinking purposes. The chemistry of water samples from coastal aquifer was interpreted by using classical Piper diagrams. The study indicates that Ca-Mg-HCO3 and Ca-Mg-Cl are the dominant hydrochemical facies followed by Na-Cl and Ca-Mg-SO4 facies. Gibb's plot reveals that the mechanisms responsible for controlling chemical composition of the groundwater are both rock-water interaction and evaporation. Source

In the title compound, C17H13NO2, two molecules crystallize in the asymmetric unit. The dihedral angle between the mean planes of the quinoline and benzene rings are 78.3(4) and 88.2(3)°. The carboxylate group is twisted slightly from the quinoline ring by 7.1(2) and 13.3(4)°, respectively. In the crystal, weak C-H⋯O interactions are observed. Further stabilization is provided by weak π-π stacking interactions, with centroid-centroid distances of 3.564(9)/3.689(2) and 3.830(1)/3.896(5)Å, respectively. Source
