2-Amino-5-oxo-4-(thio-phen-2-yl)-5,6,7,8-tetra-hydro-4-chromene-3-carbo-nitrile.

The crystal structure of the title compound, CHNOS, reveals two symmetrically independent mol-ecules within the asymmetric unit. Each mol-ecule contains a chromenone core attached to a 2-thio-phene ring, cyano, and amino groups. The 2-thio-phene ring of one of the two mol-ecules in the asymmetric unit was found to be disordered over two positions, with the major component having a site occupancy factor of 0.
