title: Crystal structure of 2-amino-3-cyano-4-(4-meth-oxy-phen-yl)-4H-1-benzo-thieno[3,2-b]pyran.
abstract: The three fused five- and six-membered rings in the title compound, C19H14N2O2S, are virtually coplanar, with the maximum deviation from the mean plane being 0.060 (1) Å. This benzothieno[3,2-b]pyran ring system is nearly perpendic-ular to the plane of the 4-meth-oxy-phenyl ring, forming a dihedral angle of 83.65 (5)°. In the crystal, mol-ecules are linked by pairs of N-H⋯N hydrogen bonds into inversion dimers. The dimeric units are further connected by an N-H⋯O hydrogen bond into a tape running along the b axis. The tapes are linked together by C-H⋯N and π-π inter-actions [centroid-centroid distance = 3.7743 (8) Å], forming a three-dimensional network.
