SYNTHESIS AND CHARACTERISATION OF A HETERODINUCLEAR RUTHENIUM(II)-PALLADIUM(II) COMPLEX WITH TWO DIFFERENT CYCLOMETALLATING SITES

摘要

A bis-cyclometallating ligand bearing two different terdentate coordination sites (N-C-N: dipyridyl-benzene; P-C-P: diphosphaalkene-benzene moieties) has been synthesised. Selective reactions of appropriate metal complex precursors afforded a heterodinuclear ruthenium(II)-palladium(II) complex characterised by H-1, P-31 NMR spectroscopy and FAB-MS techniques. We have compared its electrochemical and spectroscopic properties (absorption and emission) with the individual ruthenium(II) and palladium(II) subunits. [References: 34]
