The crystals of 3-indolepropionic acid have been obtained by evaporation from ethanol solution. The crystal structure of the 3-indolepropionic acid was determined by X-ray single crystal diffraction analysis. The crystal data for 3-indolepropionic acid: monoclinic, space group P2(1)/c, a = 14.3592(8) Å, b = 5.2446(2) Å, c = 12.3518(6) Å, V = 926.96(8) Å3, Z = 4, Mr = 189.21, De = 1.356 g/cm3, T = 298(2) K, F (000) = 400, R = 0.0435 and wR = 0.1010. The compound forms one-dimensional chained structure through hydrogen bonds and π-π interaction.

Herein, we report a facile synthetic methodology for the preparation of 2,3-dialkylquinolines from anilines and propionaldehydes. This cyclization involved environmentally friendly Nafion® NR50 as an acidic catalyst with microwave irradiation as the heating source. A series of substituted 2-ethyl-3-methylquinolines were prepared from various anilines and propionaldehyde derivatives through this protocol with good to excellent yields. Some new chemical structures were confirmed by X-ray single-crystal diffraction analysis and the related data were provided. The plausible reaction mechanism studies are also discussed.

AbstractThe cyano-bridged heteronuclear coordination polymer of zinc(II)/nickel(II) has been prepared by N-(2-hydroxyethyl)-ethylendiamine (hydet-en), alternatively named 2-(2-aminoethylamino)-ethanol and characterised by IR and thermal analysis. In the bimetallic complex, the decomposition of hydet-en ligands is seen to be endothermic whereas that of the cyano ligands is found to be exothermic. The crystal structure of the complex has been determined by single-crystal X-ray diffraction. The crystal structure of the zinc(II)-nickel(II) complex consists of a one-dimensional polymeric chain –Zn(hydet-en)
