Abstract
AbstractEight new chiral triorganotin(IV) complexes, (R3Sn)2[C8H14(COO)2] (R = C6H5: 1; PhCH2: 2), {(R3Sn)2[C8H14(COO)2]}n(R = nBu: 3; Me: 4), (R3Sn)2[C6H8(COO)2] (R = C6H5: 5; PhCH2: 6), {(R3Sn)[C6H8(COO)2]}n (R = nBu: 7), and {(R3Sn)2[C8H14(COO)2]}n (R = Me: 8) have been synthesized by the reaction of (+)‐(1R,3S)‐camphoric acid and meso‐cis‐4‐cyclohexene‐1,2‐dicarboxylic acid with triorganotin(IV) chloride in the presence of sodium ethoxide. All of the complexes were characterized by elemental analysis, FT‐IR, NMR (1H, 13C and 119Sn) spectroscopy, and TGA. Except for 2, 5, and 6, all of the complexes were also characterized by X‐ray crystallography. Complex 1 has a dinuclear structure, and complex 3 has a 1D zigzag chain structure and forms a 3D organotin framework through weak intermolecular O···Sn interactions. Complex 7 also has a 1D zigzag chain structure in which meso‐cis‐4‐cyclohexene‐1,2‐dicarboxylic acid acts as a bidentate ligand coordinated to tri‐n‐butyltin(IV) ions. Complexes 4 and 8 have 2D network structures in which (+)‐camphoric acid and meso‐cis‐4‐cyclohexene‐1,2‐dicarboxylic acid act as tetradentate ligands coordinated to trimethyltin(IV) ions.(© Wiley‐VCH Verlag GmbH & Co.
