Figure 4
Packing diagram showing the parallel stacking of molecules in (I). Intermolecular hydrogen bonding, N10′—H10′⋯O4i (solid black dashed line), links the molecules into chains and the π-stacking of both the acridine moieties (acridine-to-acridine) and the thiazolidine rings (thiazolidine-to-thiazolidine) is evident. Intramolecular hydrogen bonding, C1′—H1′⋯N12′ (hollow dashed line), is also present. For clarity, only H atoms involved in hydrogen bonds are depicted. [Symmetry code: (i) x, y, z − 1.] |
