Binuclear cyclopalladated benzo[h]quinoline and 2-tolylpyridine complexes with the bridging 2-mercaptopyridine ligand

Abstract

The planar binuclear cyclometalated Pt(II) and Pd(II) complexes with the metal–metal bonding are of wide interest due to the important role of such complexes in the metal catalysis [1], their anti-carcinogenic properties [2], and the possibility of their use as the components in light-emitting diodes [3, 4]. This work presents the results of a study of spectroscopic and electrochemical characteristics of the [Pd(C^N)(μ-S^N)]2 complexes, where (C^N) denotes the deprotonated forms of benzo[h]quinolone and 2-tolylpyridine, and (S^N) corresponds to that of 2-mercaptopyridine.
