Abstract

Intervalence charge transfer properties were studied for a set of mixed valence complexes incorporating Ru(III) and Fe(II)-centres linked by various saturated and unsaturated bridging ligands (BL). Studies reveal that degree of ground state electronic interaction and coupling between Ru(III) and Fe(II)-centrescanbe attenuated by changing the nature of the bridging ligand. Further, inclusion of the bridging ligand with interrupted π-electron system in a β-CD cavity initiate an optical electron transfer from Fe(II) to Ru(III) which is otherwise not observed.

  16. Pseudo first order nature of the reaction for the formation of complexXI andXII through aqua substitution of Fe(CN)5(H2O)3-by complexIX andX respectively (scheme 1) was established by studying kinetics with different [dta)RuBL•β-CD]-(where BL is bpete or bpp)keeping [Fe(CN)5(H2O)3-] constant. A plot ofkobs vs [(edta)BL-]gives a straight line with a small intercept, which signifies a reverse aquation reaction. [dta)RuBL•β-CD] was varied from 6.0 × 10-4 to 2.0 × 10-3 M; [Fe(CN)5(H2O)3-] = 1-0 × 10-4M, μ = O.1 M (KCl) and 2.0 × 10-3M β-CD (was added to ensure that that (edta)RuBL-species exist only as (edta)RuBL•β-CD. Pseudo first order conditions using excess of (edta)RuBL•β-CD was followed for evaluation of thermodynamic parameters; [(edta)RuBL•β-CD] = 1.0 x 10 M, [Fe(CN)5(H2O)3-] = 1.0 × 10-4 M, [μ]= 0.1 M (KCl) and [μ-CD] = 2.0 x 10 M. Negative ΔS# and low ΔH# values for this reaction suggest an interchange associative pathway for the substitution reaction.

  17. Kinetics of thein situ formation of [2]rotaxane complexes through decomposition of complexesVI andVII were also studied. For these reactions, addition of (edta)RuBL•β-CD and/or β-CD has no effect on observed rate constant; which signifies the dissociation of Fe-Py bond in dta)Ru(μ-BL)Fe(CN)53-is rate determining step. Still excess β-CD was used to ensure complete inclusion of BL in CD cavity. Reaction parameters: 1 ml of 1.0 × 10-3M [(edta)RuBL], 0.1 ml of 1.0 × 10-4 M Fe(CN)5(H2O)3- and 0.9 ml KCl of appropriate concentration (to maintain ionic strength of 0.1 M) were mixed and kept in dark for 15 mto complete the formation of dta)Ru(μ-BL)Fe(CN)54-, then 1 ml of 6.0 × 10-3M β-CD was added and the change in absorbance with time was monitored at 1000 nm. Pseudo-first-order rate constant was found to be independent of the initial concentration of dta)Ru(μ-BL)Fe(CN)54-(BL = Py(CH2)nPy;n = 2 or 3). Furthermore, the observed dissociation rate constant for this reaction is close to that reported for reverse aquation reaction of complex (edta)Ru(μ-bpp)Fe(CN)5/4-. Inclusion of heterocyclic spacer group BL in (edta)RuBL by β-CD and formation of [2]rotaxane by reaction of dta)RuBL•β-CD-with Fe(CN)5(H2O)3-is much faster than the reverse aquation reaction of Py-Fe(CN)5 /3- centre. Activation parameters for this reaction (table 1) also confirm this presumption. Near zero or small ΔS# value for this reaction suggests a dissociative pathway

  18. On addition of excess DMSO in solution of complexXI orXII, a decrease in absorbance with time at 1000 nm was registered. Kinetics of decomposition of [2]rotaxane (complexesXI andXII) at 1000 nm in presence of excess DMSO and β-CD is studied. Reaction parameters: [dta)Ru(μ-BL•β-CD)Fe(CN)54-](complexXI orXII) = 1.0 × 10-4 M; [DMSO] = 0.2 M and μ = 0.1 M (KCl).The observed first order dissociation constant and activation parameters are summarized in table 1. [Fe(CN)5(H2O)]3-species produced by dissociation of complexXI orXII reacts with DMSO to form a kinetically inert complex [Fe(CN)5DMSO]3-and thereby quenches the further possibility of binuclear complex formation. High ΔH# and small positive ΔS# values for this reaction are indicative of the dissociative pathway.kd/dmso, observed dissociation rate constants forXI andXII in presence of DMSO, decreases significantly upon inclusion of ligand in β-CD cavity (table 1). This further demonstrates that β-CD inclusion of the BL enhances the stability of binuclear complexes
