Redox responsive bi/tri-nuclear complexes incorporating ferrocenyl unit: Synthesis, characterization, physicochemical studies and X-ray structure of [C5H5FeC5H4CH = CHC5H4N-CH3]PF6 with a mirror creating disorder
(Trans-1-(4-pyridyl)-ethylene) ferrocene, L reacts with K[RuIII(edtaH)]Cl to form binuclear complex. K[RuIII(edtaH)]Cl exist as RuIII(edtaH)(H2O) in aqueous solution and substitution of the aqua molecule by L occurs within the stopped flow time scale. Rate constants for the reaction are 1620 ¡À 20, 2080 ¡À 35, 2690 ¡À 50 M-1 s-1 at 28, 34 and 39.9C, respectively [DeltaH# is 30.3 ¡À 1.1 kJ mol-1 and DeltaS# is -124 ¡À 4 J K-1 mol-1]. RII(2,2?-bipy)2Cl2 reacts with L to form bi/trinuclear complexes, [RuII(2,2?-bipy)2LCl]PF6 and [RuII(2,2?-bipy)2L2](PF6)2, depending on the reaction conditions. Luminescence of the RuII(2,2?-bipy)2(py)2+2 center in the trinuclear complexes is completely quenched presumably through energy transfer pathway. There exist a moderate to weak electrochemical interaction between the two redox centers either in N-methylated form of L or in the bi/trinuclear complexes derived from Ru(II) or Ru(III). All these new bi/trinuclear complexes are characterized by physicochemical methods. Single crystal X-ray structure of [L-CH3]PF6 is reported. A very low value of powder SHG efficiency observed earlier for this salt can now be well understood in terms of the centrosymmetric molecular arrangement created due to the disorder in the crystal.
Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data.COA of Formula: C20H16Cl2N4Ru, If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 15746-57-3, in my other articles.
