Bis(3-hydroxy-2-methyl-4-pyronato) complexes of cobalt(II), nickel(II), copper(II), and zinc(II) have been prepared: CoL<SUB>2</SUB>(OH<SUB>2</SUB>)<SUB>2</SUB>, NiL<SUB>2</SUB>(OH<SUB>2</SUB>)<SUB>2</SUB>, CuL<SUB>2</SUB>, and [ZnL<SUB>2</SUB>(OH<SUB>2</SUB>)<SUB>2</SUB>]·1/2H<SUB>2</SUB>O. The 2,2′-bipyridine-(bpy) and 1,10-phenanthroline(phen) adducts of these complexes were also synthesized: CoL<SUB>2</SUB>(bpy), CoL<SUB>2</SUB>(phen), NiL<SUB>2</SUB>(bpy), ZnL<SUB>2</SUB>(bpy), and ZnL<SUB>2</SUB>(phen). Based on the magnetic, spectral, and thermogravimetric data, the structures of these complexes are proposed: all of the cobalt(II), nickel(II), and zinc(II) complexes are octahedral, and CuL<SUB>2</SUB> is square planar. The NMR spectra of the zinc(II) complexes are discussed.
