Coordination Chemistry of Organotin(Ⅳ) Dithiocarbamate Complexes
Ok-Sang Jung, Youn Soo Sohn*
Coordination chemistry of organotin(Ⅳ) dithiocarbamate complexes has been examined in terms of far infrared and 119Sn-NMR spectroscopies. Although the Sn-S stretching vibrational bands of the complex could not be correlated with the bonding nature of the dithiocarbamate ligand, 119Sn chemical shifts were sensitive enough to distinguish clearly the coordination number of tin, and as such the bonding mode of the dithiocarbamate ligand could be indentified to be monodentate or bidentate. Thus the 119Sn-NMR study on new cyclohexyltin(Ⅳ ) dithiocarbamate complexes along with the known complexes suggests that the bonding mode of the dithiocarbamate ligands and the consequent coordination number of tin are determined mainly by the inductive effects of the organic groups attached to the tin atom.
