The crystal Structure of 7-(1H-pyrrol-1-yl)-4-methyl-2H-1-benzopyran-2-one was determined by X-ray diffraction. The crystal, C14H11NO2, belongs to space group C2/c with cell dimensions a = 17.74(1)Å, b = 7.343(3)Å, c = 16.242(6)Å, β = 92.349(9)°. The final R value is 0.047 for 2301 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 3.74(5)°.
