2-(2-Chlorobenzoyl)-1-(3,4-dimethoxyphenyl)-3-iodoquinolin-4(1H)-one

Abstract

In the title compound C 24 H 17 ClINO 4 , the iodoquinolinyl moiety (r.m.s. deviation = 0.044 Å ) makes dihedral angles of 87.44 (10) and 88.64 (10) with the chloro-and methoxy-substituted benzene rings, respectively. The methoxy groups are present in synperiplanar and antiperiplanar conformations with respect to the benzene ring they are bound to, as indicated by the C-C-O-C torsion angle values of À16.2 (3) and 177.6 (2) , respectively. The crystal structure features relatively strong methoxybenzene-C-HÁ Á ÁO(quinolinyl) hydrogen bonds, leading to helical supramolecular chains along the a-axis direction. Additional C-HÁ Á ÁO interactions along with -stacking [intercentroid distance = 3.6070 (16) Å between quinolyl-NC 5 and C 6 rings] consolidate the three-dimensional molecular packing.
