- W744266503 abstract "The title compound 4-(2-bromophenyl)-3,4,7,8-tetrahydro-7,7-dimethyl-1-p-tolyl- quinoline-2,5(1H,6H)-dione 1 (C24H24BrNO2, Mr = 438.35) was synthesized and characterized by IR, 1H NMR and elemental analysis. The crystal belongs to monoclinic, space group C2/c with a = 27.565(14), b = 10.079(5), c = 15.917(8) , β = 111.059(9)o, Z = 8, V = 4127(4)3, Dc = 1.411 g·cm–3, μ(MoKα) = 2.011 mm–1, F(000) = 1808, the final R = 0.0417 and wR = 0.1032 for 2393 observed reflections (I 2σ(I)). X-ray analysis reveals that the pyridine ring adopts a distorted boat conformation, while another six-membered ring takes a half-chair conformation. In addition, there are non-classical hydrogen bonds of C–H···O and C–H···Br in the structure. The short distance (3.481) between the adjacent 2-bromophenyl rings indicates the existence of π-π interaction." @default.
