title: Benzyl N'-benzhydrylidene-hydrazine-carbodithio-ate.
abstract: In the title mol-ecule, C(21)H(18)N(2)S(2), the C=N-N angle of 117.6 (2)° is significantly smaller than the ideal value of 120° expected for sp(2)-hybridized N atoms. This is probably a consequence of repulsion between the nitro-gen lone pairs and the adjacent N atom, as suggested in Zheng, Qiu, Lin & Liu [Acta Cryst. (2006), E62, o1913-o1914]. The two neighbouring benzene rings form a dihedral angle of 75.95 (3)° with each other, while subtending dihedral angles of 84.18 (3) and 8.44 (2)° with the third ring in the structure.
