| Description |
The oxidation of [RuII(tpy)(pic)H2O]+ (tpy = 2,2′,6′,2′′-terpyridine; pic− = picolinate) by peroxidisulfate
(S2O8
2−) as precursor oxidant has been investigated kinetically by UV-VIS, IR and EPR spectroscopy.
The overall oxidation of Ru(II)- to Ru(IV)-species takes place in a consecutive manner involving oxidation
of [RuII(tpy)( pic)H2O]+ to [RuIII(tpy)( pic)(OH)]+, and its further oxidation of to the ultimate product
[RuIV(tpy)( pic)(O)]+ complex. The time course of the reaction was followed as a function of [S2O8
2−],
ionic strength (I) and temperature. Kinetic data and activation parameters are interpreted in terms of an
outer-sphere electron transfer mechanism. Anti-microbial activity of RuII(tpy)(pic)H2O]+ complex by
inhibiting the growth of Escherichia coli DH5α in presence of peroxydisulfate has been explored, and
the results of the biological studies have been discussed in terms of the [RuIV(tpy)( pic)(O)]+ mediated
cleavage of chromosomal DNA of the bacteria.
