The benzene rings are almost perpendicular to one another, making a dihedral angle of 89.14?(6)°. There are bifurcated intra-molecular C-H?O hydrogen bonds in the mol-ecular structure. In the crystal, mol-ecules are linked via C-H?? inter-actions, forming chains propagating along [100].

In M, the aza-14-crown-3-ether ring adopts a bowl conformation, with the configuration of the C-O-C-C -O-C-C-O-C polyether chain being t-g ((-))-t-t-g ((+))-t (t = trans, 180°; g = gauche, ±60°).

Project description: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.
