Complexes of Tlcl2I with Pyridine N-Oxide and some Substituted Pyridine N-Oxides

Abstract

Abstract The following compounds: TlCl2I. (PyO)2, TlCl2I. (2-PicO)2, TlCl2I. (3-PicO)2, TlCl2I. (4-PicO)2, TlCl2I. and TlCl2I. (4-MeOPyO)2 have been prepared and characterized by elemental analysis. The solids are monomers and behave as non-electrolytes in acetonitrile solution. The molecular structures of the complexes were studied on the basis of 1H NMR and IR spectra. The most probable structure is that of a trigcnal bipyramid with the halogen atoms in equatorial positions and the two ligands L in axial positions.
