Abstract
The crystal structure of {4-[3-(4-fluoro-phenyl)-acryloyl]-phenyl}-carbamic acid tert-butyl ester has been determined by X-ray diffraction, title compound crystallized in orthorhombic, P21/n space group with unit cell parameters a = 10.100(3) Å, b = 18.201(5) Å, c = 10.829(3) Å; α = 90°, β = 111.15(4)°, γ = 90°. The crystal structure of compound was stabilized by N–H…O intermolecular hydrogen bonding, the molecules are linked by C–H…F, C–H…O and C–H…H–C intermolecular interactions. The two benzenes rings are non planar with dihedral angle 11.11° and contains a single C=C double bond in a trans (E) configuration.
