title: Dibenzo[b,f][1,4]thia-zepin-11-yl-diethyl-amine.
abstract: In the title compound, C(17)H(18)N(2)S, the thia-zepine ring adopts a boat conformation and the dihedral angle between the benzene rings is 75.92 (5)°, resulting in a butterfly-like conformation. In the crystal, mol-ecules are connected via weak C(aromatic)-H⋯N contacts involving the imine N atom as acceptor and through a quite short C-H⋯π inter-action. The resulting mol-ecular chains propagate along the c-axis direction.
