Abstract
Several transition metal chelates with 2-(1-pyridine-2-thionato)benzox azole (PTBOX) and 2-(1-pyridine-2-thionato)benzothiazole (PTBTH) have been prepared and characterized. The ligands behave as a bidentate don ors coordinating through the nitrogen atom of the benzoxazole or benzo thiazole group and through the sulphur atom of the pyridine-2-thione m oiety. The ligand field spectra and the magnetic moment values suggest an octahedral geometry for the bivalent metal complexes. The Au(III) complex is proposed to have a trigonal bipyramidal stereochemistry. A chlorine-bridged dimeric structure has been suggested for the trivalen t metal complexes.
