چکیده
The title compound crystallizes as a chloro-form solvate, C(20)H(23)N(3)O(3)S·CHCl(3), with two crystallographically independent units. The independent units have distinctly different inter-action patterns between the aza-crown macrocycle and the chloro-form solvent mol-ecule. In one of them, the chloro-form mol-ecule forms C-H⋯N and Cl⋯H-C hydrogen bonds with the aza-crown macrocycle (as a proton donor and an acceptor, respectively), whereas in the other, one of the chloro-form mol-ecules is bound to the aza-crown macrocycle by an attractive Cl⋯O [3.080 (3) Å] inter-action. The aza-crown macrocycles of different units are structurally similar; the aza-14-crown-3-ether ring adopts a bowl conformation with dihedral angles between the planes of the fused benzene rings of 60.7 (1) and 68.0 (1)°. The triazinane-thione ring in both cases has a sofa conformation. The crystal packing is characterized by N-H⋯S, N-H⋯O, C-H⋯Cl and C-H⋯S hydrogen bonds.
