3,3'-Di-2-naphthoyl-1,1'-(o-phenyl-ene)dithio-urea.

ABSTRACT: In the mol-ecule of the title compound, C(30)H(22)N(4)O(2)S(2), the central benzene ring is oriented at dihedral angles of 63.83?(3) and 1.37?(3)° with respect to the naphthalene ring systems, while the two naphthalene ring systems are oriented at a dihedral angle of 62.78?(3)°. Intra-molecular N-H?O and N-H?N hydrogen bonds result in the formation of one five- and two six-membered rings. The twisting modes of the two side arms are different [C-N-C-O and C-N-C-N torsion angles = 11.1?(4) and 1.5?(3)°, respectively, in one arm, and -2.2?(4) and 0.8?(3)° in the other arm]. In the crystal structure, inter-molecular N-H?S hydrogen bonds link the mol-ecules into centrosymmetric dimers. There is a C-H?? contact between the naphthalene rings and ?-? contacts between the naphthalene rings and the naphthalene and benzene rings [centroid-centroid distances = 3.651?(1), 3.828?(1), 3.811?(2) and 3.786?(1)?Å].
