New organotin(IV) carboxylates, [n-Bu2SnL2] (1), [Et2SnL2] (2), [Me2SnL2] (3), [n-Oct(2)SnL(2)] (4), [n-Bu3SnL](n) (5), [Me3SnL](n) (6), and [Ph3SnL](n) (7), where L = 3-(4-bromophenyl)-2-ethylacrylate, were synthesized and characterized by elemental analysis, FT-IR, and multinuclear NMR (H-1, C-13, and Sn-119). Spectroscopic studies confirm coordination of L to the organotin moiety via COO group. Single-crystal X-ray analysis reveals bridging mode of coordination in 6. Packing diagram established a supramolecular cage-like structure for 6 due to Sn-O interactions (3.287 angstrom). Subsequent antimicrobial activities proved them to be active biologically.
