Elemental analyses and spectral (FT-IR, UV-Vis and 1H, 31P NMR) studies of all the new synthesized complexes suggest the presence of an octahedral environment around the RuII ion. Cyclic voltammograms of all the complexes display oxidation and reduction potentials. Superoxide dismutase activity (SOD) of these complexes has also been examined. These complexes were also subjected to study their biocidal activity against Staphylococcus epidermidis, Escherichia coli, Botrytis cinerea and Aspergillus niger.
