Crystal Structure of a Chalcone Derivative

Abstract

The crystal and molecular structure of 1-(4-methoxyphenyl)-3-(phenyl)-2-propen-l -one derivative is determined by X-ny diffraction method. The compound. C16H1402. crystallises in the orthorhombic space group Pbca with a = 10.921(2) A. b = 30.583(1) A. c = 7.535(3) A, V = 2516.7(9) .k3, Z = 4, Dcdc = 1.242 Mg/m', ji = 0.327 mm-', F~o = 504, h(MoKa) = 0.71069 A and the structure was refined to R = 0.044.

1-(1-Benzofuran-2-yl)-3-(4-chlorophenyl)prop-2-en-1-one

“…The dihedral angle between the benzofuran ring system and the chlorophenyl ring is 10.53 (6)°. Bond distances within the aromatic rings are in agreement with those observed in related structures (Devarajegowda et al, 2001;Kant et al, 2009).…”
