Abstract
Abstract A novel family of the general type cis -[Ru II (dppe)LCl 2 ] {L = C 6 H 5 N NC(COCH 3 ) NAr, Ar = 2,4,6-trimethylphenyl (L 1 ), 2,5-dimethylphenyl (L 2 ), 4-tolyl (L 3 ), phenyl (L 4 ), 4-methoxyphenyl (L 5 ), 4-chlorophenyl (L 6 ), 4-nitrophenyl (L 7 ), 2,5-dichlorophenyl (L 8 ); dppe = Ph 2 P(CH 2 ) 2 PPh 2 } has been synthesized. These complexes have been characterized through analytical, spectroscopic (IR, UV–Vis, and NMR) and electrochemical (cyclic voltammetry) techniques. In addition, complex 4 (where L = L 4 ) has been further characterized by X-ray diffraction analysis. Crystallographic, electrochemical and electronic spectral data are all consistent with the azomethine ligands possessing strong π-acceptor properties. These π-acceptor properties can be “tuned” by a judicious choice of substituent on the azomethine ligand.
