With reference to the quinolin-3-yl group, the 3-(thiophen-2-yl)prop-2-en-1-one residue is almost perpendicular, with all but the carbonyl O atom lying to one side of the plane. This conformation is reflected by the C - C - C - C torsion angles of -102.2 (3) and 81.1 (3)° in the two independent molecules. The dihedral angle formed between the 13 non-H atoms directly associated with the quinolin-3-yl group and the thiophen-2-yl ring is 87.70 (11)° [83.85 (10)° for the second independent molecule]. The presence of C - H⋯O, C - H⋯N and π-π interactions [centroidcentroid distance = 3.5590 (12) Å] lead to supramolecular chains along the caxis direction. These are connected along the aaxis direction by C - H⋯π interactions. The resultant supramolecular layers stack along the b axis.  ISSN : 1600-5368  Journal Name : Acta Crystallographica Section E: Structure Reports Online  Volume : 67  Issue Number : 9  Publishing Year : 1432 AH 2011 AD  Article Type : Article  Added Date : Wednesday, December 7, 2011  Researchers Researcher Name (Arabic) Researcher Name (English) Researcher Type Dr Grade Email R Prasath Prasath, R Researcher Doctorate   P Bhavana Bhavana, P Researcher Doctorate juliebhavana@yahoo.co.in Seik Weng Ng Ng, Seik Weng Researcher Doctorate seikweng@um.edu.my E R T Tiekink Tiekink, E R T Researcher Doctorate edward.tiekink@gmail.com Files File Name Type Description  31590.pdf pdf Abstract Back To Researches Page
