1-(Naphthalen-1-yl)-3-[(thio­phen-2-yl)carbon­yl]thio­urea

In the title compound, C(16)H(12)N(2)OS(2), the dihedral angles between the mean planes of the central thio­urea core and the thio­phene ring and the naphthalene ring system are 1.8 (2) and 6.45 (18)°, respectively. The mol­ecule adopts a trans–cis conformation with respect to the position of thio­phenoyl and naphthyl groups relative to the S atom across the thiourea C—N bonds. Both the thio­phene ring and the sulfanyl­idene S atom are disordered over two sets of sites with occupancies of 0.862 (3):0.138 (3) and 0.977 (3):0.023 (3), respectively. An intra­molecular N—H⋯O hydrogen bond is observed. The crystal packing features two N—H⋯S hydrogen bonds.
