Trinuclear complexation of 2,6-bis(acetylacetoxymethyl)pyridine with Pd(II) and Cu(II) ions

Abstract Treatment of [PdCl 2 (PhCN) 2 ] with 2,6-disubstituted pyridines (L) gave a new series of trans -[PdCl 2 L 2 ] complexes. β-Ketoester substituents in the ligands were found to form OO chelate compounds with a Cu(II) ion. The Pd(II) complex of 2,6-bis(acetylacetoxymethyl)pyridine reacted with copper(II) acetate in dioxane to yield a (Cu(II), Pd(II), Cu(II)) trinuclear complex, which incorporated dioxane in the crystals. NMR, IR and reflectance spectra of the products were examined.
