title: 2,6-Bis(2-hydroxy-ethyl)-8b,8c-diphenyl-perhydro-2,3a,4a,6,7a,8a-hexa-azacyclo-penta-[def]fluorene-4,8-dithione.
abstract: In the title mol-ecule, C(24)H(28)N(6)O(2)S(2), the dihedral angle between the aromatic ring planes is 42.2 (1)°. In the crystal structure, the hydr-oxy groups are involved in O-H⋯S hydrogen bonding, which links the mol-ecules into corrugated layers propagating parallel to the bc plane.
