Crystal Structure of 7-(1H-pyrrol-1-yl)-4-trifluoromethyl-2H-1-benzopyran-2-one has been determined by X-ray diffraction. The crystal, C14H8NO2F3, belongs to space group P21/n with cell dimensions of a = 10.201(6)Å, b = 8.481(8)Å, c = 13.864(8)Å, β = 109.75(2)°. The final R value is 0.041 for 2602 reflections (I > 2.00 σ(I)). The coumarin and the pyrrole moieties are almost coplanar. The dihedral angle between the least-squares planes of the aromatic ring and the pyrrolyl group is 6.98(4)°.
