title: 3-(2-Oxo-2,3,4,5-tetra-hydro-furan-3-yl)-1-benzofuran-2-carbonitrile.
abstract: The asymmetric unit of the title compound, C(13)H(9)NO(3), consists of two crystallographically independent mol-ecules. In each mol-ecule, the tetra-hydro-furan (THF) ring adopts an envelope conformation with one of the methyl-ene C atoms positioned at the flap. The dihedral angles between the mean plane of the THF and the benzofuran ring system are 70.85 (5) and 89.59 (6)°. In the crystal, mol-ecules are stacked in a column along the a-axis direction through C-H⋯O hydrogen bonds, with columns further linked by C-H⋯N and C-H⋯O inter-actions.
