摘要: The synthesis and characterization of the isomeric ruthenium complexes with general formula cis- trans-[Ru(trpy)(qc)X]n+ (trpy is 2,2':6',2″-terpyridine, qc 8-quinolinecarboxylate, cis-1 trans-1, X = Cl, n 0; cis-2 trans-2, X=OH2, 1) respect to relative disposition carboxylate ligands are reported. For comparison purposes, another set trans-[Ru(trpy)(pic)(OH2)]+ (pic 2-picolinate (cis-3, trans-3)) have been prepared. a ligand show more distorted geometry compared pic ligand. In all cases, trans isomers lower potential values for redox couples cis isomers. Complexes trans-2 six-member chelate rings higher catalytic activity than cis-3 trans-3. Overall, it was shown that electronic perturbation metal center exerted by different orientation significantly influences both properties performance.
