Abstract

The synthesis of four new organotin carboxylates, [(t-C4H9)2Sn(L1)2] (1), [(t-C4H9)2Sn(L2)2] (2), [{(n-C4H9)2Sn(L1)}2O]2 (3) and [{(n-C4H9)2Sn(L2)}2O]2 (4), is reported. All complexes have been characterized by 1H, 13C{1H} and 119Sn{1H} NMR spectroscopy, elemental analysis and single crystal X-ray diffraction. Complexes 1 and 2 are monomers and contain a six-coordinated tin centre, while both five- and six-coordinated tin centres are observed in the tetrameric structures of 3 and 4. All complexes selectively recognize Cu(II) and Fe(III) ions in solution. Complex 1 was found to be the best one for sensing those ions among all complexes.
