The pyridine(py), 4-methylpyridine(4-Me-py) and 4-cyanopyridine(4-CN-py) adducts of bis(3-hydroxy-2-methyl-4-pyronato) complexes (ML<SUB>2</SUB>) of cobalt(II), nickel(II), and zinc(II) have been synthesized: CoL<SUB>2</SUB>(py)<I><SUB>n</SUB></I> (where <I>n</I>=2 or 3), NiL<SUB>2</SUB>(py)<SUB>3</SUB>, ZnL<SUB>2</SUB>(py), ML<SUB>2</SUB>(4-Me-py)<SUB>2</SUB> (where M=Co(II), Ni(II), and Zn(II)), ML<SUB>2</SUB>(4-CN-py) (where M=Co(II) and Zn(II)), and NiL<SUB>2</SUB>(4-CN-py)<SUB>2</SUB>. Based on the magnetic, spectral, and thermogravimetric data, three of these complexes, ZnL<SUB>2</SUB>(py) and ML<SUB>2</SUB>(4-CN-py) (where M=Co(II) and Zn(II)), are presumed to have a five-coordinate structure, while the other complexes are presumed to be octahedral. In the case of the 4-cyanopyridine complexes, the infrared spectra show that the pyridine-ring nitrogen is linked to the metal ion and that the nitrogen atom of the nitrile group is not coordinated.
