Metal-Ion-Directed Synthesis of Homo- and Heteronuclear Dimetallic Schiff Base Podates. II.

Homodinuclear complexes with magnesium(II), calcium(II), and barium(II) ions and heterodinuclear complexes with calcium(II) or cadmium(II) and lanthanide(III) ions containing Schiff base open-chain ligand terminated by one amine and one carbonyl group were prepared as a result of the partial Schiff base condensation reaction between 2,6-diacetylpyridine and 4-methyl-1,2-phenylenediamine in the presence of the appropriate ions acting as templates. The complexes were characterized by spectroscopic methods (IR, 1H NMR, FAB-MS), thermogravimetric and elemental analyses.
