Studies on metal carboxylates. Part IV. Pyridine-2,6-dicarboxylate complexes of cobalt(II), nickel(II), rhodium(II), and rhodium(III). Synthesis, spectral and magnetic properties, and a study of rhodium 3d binding energies by X-ray photoelectron spectroscopy

Abstract

The synthesis and characterization of the 1 : 1 and 1 : 2 complexes of cobalt(II) and nickel(II) with pyridine-2,6-dicarboxylic acid (dpcH2) are reported. The 1 : 2 complexes are shown to have the structure M(dpcH)2,3H2O, containing monoanionic terdentate dpcH ligand molecules, with three molecules of ‘lattice’ water, whereas the 1 : 1 complexes M(dpc),3H2O are six-co-ordinate and contain co-ordinated water. Anhydrous polymeric [Co-(dpc)]n has been prepared and its chemical reactivity investigated. Rhodium(II) acetate reacts with dpcH2 to afford a rhodium(II) complex Rh(dpc),3H2O. The rhodium(III) complexes Na[Rh(dpc)2],2H2O and Ph4As-[Rh(dpc)2],xH2O have also been prepared. Characterization of the rhodium complexes has included a study of their X-ray photoelectron spectra and a measurement of the rhodium 3d3/2 and 3d5/2 binding energies.
