Abstract
We prepared 8 new organotin compounds with the general formulae [R3SNL], where R = Me (1), Bu (2); Ph (3), and Cy (4) and [R2SnL2], where R = Me (5), Et (6), Bu,(7), Oct (8), and L = piperonylic acid, and characterized them by elemental analyses, IR, spectra, and multinuclear NMR (H-1, C-13, and Sn-119). The structure of 5 was confirmed by single crystal X-ray crystalloographly. The geometry around the tin atom was compared in both solution and solid state. Crystals of 5 are monoclinic with the space group P2(1)/c. The tin geometry is skew trapezoidal bipyrarnidal, with 2 longer and 2 shorter Sn-O bonds; thus. the ligand chelates the Sn center in an asymmetric way. The synthesized compounds were also screened for antibacterial, antifungal, brine-shrimp lethality, and potato disc antitumor activity.
