The synthesis and properties of a series of potentially bi-, tri- and tetra-dentate ligands containing various combinations of antimony and sulphur and antimony and oxygen donors, is described.Included are SbPhn(o-C6H4OMe)3-n (n = 0, 1, 2); SbMe2(o-C6H4OMe); SbPhn(o-C6H4SMe3)3-n (n = 0, 1, 2); SbMe2(o-C6H4SMe); MeS(CH2)3SbR2 (R = Me, Ph) and S(CH2CH2CH2SbPh2)2.Attempts to prepare ligands with dimethylene backbones including (R2SbCH2CH2)2S (R = Me, Ph) failed.The ligands were characterised by analysis, 1H NMR and mass spectra, and by the preparation of quaternary derivatives.
