1-(2-Furo-yl)-3-(1-naphth-yl)thio-urea

Abstract

In the title compound, C16H12N2O2S, the carbonyl-thio-urea group forms dihedral angles of 75.4 (1) and 13.1 (2)°, respectively, with the naphthalene ring system and furan ring. The mol-ecule adopts a trans-cis configuration with respect to the positions of the furoyl and naphthyl groups relative to the S atom across the thio-urea C - N bonds. This geometry is stabilized by an N - H⋯·O intra-molecular hydrogen bond. In the crystal structure, mol-ecules are linked by N - H⋯S hydrogen bonds, forming centrosymmetric dimers which are inter-linked through C - H⋯π inter-actions.
