文摘

A series of four new bis-Pb>2b>Nb>2b> (Pb>2b>Nb>2b> = 1,5-diaza-3,7-diphosphacyclooctane) Pd(II) complexes were synthesized and characterized by spectroscopy, electrochemistry, and X-ray crystallography. The compounds crystallize in square planar or tetrahedrally distorted geometries and exhibit a single quasi-reversible 2e^{鈥?/sup> Pd(II/0) redox couple in voltammetric studies. [Pd(PPhb>2b>NBnb>2b>)b>2b>]2+ and [Pd(PMeb>2b>NPhb>2b>)b>2b>]2+ were tested for electrochemical COb>2b> reduction in the presence of excess protons and found to preferentially produce Hb>2b>.}
