Second monoclinic form of (E)-3-(4-fluorophenyl)-1-phenylprop-2-en-1-one

Abstract

The unit-cell dimensions and space group of the second monoclinic polymorph of the title compound, C15H11FO, differ from those of the previously reported form [Jing (2009 ▶). Acta Cryst. E65, o2515]. The title compound shows an E conformation of the C=C bond with the 4-fluoro­phenyl group opposite to the benzoyl group. The torsion angle of between the planes of the 4-fluoro­phenyl and benzoyl groups is 10.53 (6)°. In the crystal, weak C—H⋯O and C—H⋯F inter­actions form a cross-linked packing motif, building sheets parallel to (-102).

“…Chalcones and their derivatives are interesting materials for their biological activities such as anti-viral, anti-malarial, anti-cancer, antioxidant, anti-inflammatory, antifungal, antileishmanial, anti-tubercular, anti-hyperglycemic properties [6][7][8][9][10][11]. They are also used in different applications such as agriculture [12], cosmetics and manufacture of pesticides [13].…”
