Abstract
The self-assembly of di (p-methylphenyl) oxide (Tol2SnO) with 3-(1,3-Dioxo-1H,3H-benzo [de]isoquinolin-2-yl)-propionic acid (HL1) and 3-(1,3-Dioxo-1,3-dihydro-isoindol-2-yl)-propionic acid (HL2) produced novel organotin carboxylates (TolSnOL1)6 (complex 1) and (TolSnOL2)6 (complex 2) (Scheme 1). Complexes 1 and 2 were characterized by the methods of elemental analysis, IR, 1H, 13C and 119Sn NMR spectroscopy. It has been revealed by single crystal X-ray study that 1 and 2 are mono-organotin carboxylates possessing hexanuclear cage - “Sn6O6” unit, which presented as a drum. The ligands in the complexes chelate with two tin atoms and adopt bidentate coordination. The molecules of 1 and 2 build their complicated 3D structures via intermolecular π···π interactions and H-bonds. The supramolecular structures of the complexes are discussed in detail. The preliminary fluorescence activity of 1 and antitumor activities of 1 and 2 were also studied.
