1-Benzoyl-3-[4-(3-benzoyl­thio­ureido)phen­yl]thio­urea

摘要

The mol­ecule of the title compound, C22H18N4O2S2, lies across a crystallographic inversion centre. The mol­ecule adopts a syn–anti configuration with respect to the positions of the carbonyl groups and terminal phenyl rings relative to the thione S atom across the C—N bond. There are two intra­molecular N—H⋯O and C—H⋯S hydrogen bonds within each molecule, resulting in the formation of four six-membered S(6) rings. The central and terminal rings make a dihedral angle of 13.55 (15)°. In the crystal, mol­ecules are linked by inter­molecular C—H⋯S hydrogen bonds, forming R 2 2(14) rings and resulting in zigzag chains.
