Electrochemical disproportionation in new ruthenium (II) nitro complexes with 2,4,6-tris(2-pyridyl)-1,3,5-triazine detected by IR spectroelectrochemistry with an OTTLE cell

The syntheses and characterization of new nitro complexes of Ru(II) with 2,4,6-tris(2-pyridyl)-1,3,5-triazine(tptz) and different substituted bipyridines are reported. A disproportionation reaction can occur after applying an oxidation potential corresponding to the couple RuII/RuIII forming the nit...

Descrição
Resumo:The syntheses and characterization of new nitro complexes of Ru(II) with 2,4,6-tris(2-pyridyl)-1,3,5-triazine(tptz) and different substituted bipyridines are reported. A disproportionation reaction can occur after applying an oxidation potential corresponding to the couple RuII/RuIII forming the nitrate and the nitrosyl complexes, which were detected by cyclic voltammetry. This reaction was confirmed by IR-spectroelectrochemistry with an OTTLE cell, for the first time. Additionally, for 2,2′-bipyridine we have obtained as ClO4 − salt a new nitrosyl complex which presents an elevated IR stretching frequency.
