speciation of all of these systems (with the exception of the Ru–1,4-benzodihydroxamic acid and Ru–N-methylbenzohydroxamic systems) in aqueous solution was investigated. We previously proposed that nitrosyl abstraction from hydroxamic acids by RuIII involves initial formation of RuIII-hydroxamates. Yet, until now, no data on the rate of nitric oxide (NO) release from hydroxamic acids has been published. We
