Synthesis and characterization of monometallic and bimetallic complexes of rhenium(I) and ruthenium(II) with 4,4 '-bipyridine as ligand-bridge.

Abstract

A new Rhenium (I) and Ruthenium(II) bimetallic polipyridilcarbonil complex and the corresponding monometallic precursor complexes were prepared. The compounds were characterized physically and spectroscopically (Elemental Analysis, Conductivity, Cyclic Voltammetry, IR-FT, RMN-H and UV-Visible). The results are consistent with the [Re(CO)(3)(2,2'-biquinoline)(4,4'-bipiridine](CF3SO3) and RuCl2 (CO)(2)(2,2'-biquinoline) formulation for the monometallic precursor complexes and with the [(CO)3 (2,2'biquinoline)Re(4,4'-bipiridine)RuCl (CO)(2) (2,2'-biquinoline)] formulation for the bimetallic complex.
