The partial Schiff base condensation reactions between 2,6-diacetylpyridine and 1,3-phenylenediamine in the presence of scandium(III), yttrium(III) and lanthanum(III) ions as template agents afford new mono- and dinuclear hexadentate complexes of podate type, depending on the molar ratio of starting materials used in the synthesis. They were characterized by IR, UV-VIS, 1H NMR, and mass spectral data as well as by thermogravimetric and elemental analyses.
