Helpful correlations to estimate the pK(a) of coordinated HNO: a potential-pH exploration in a pendant-arm cyclam-based ruthenium nitroxyl
The acid-base speciation of coordinated azanone (HNO) remains a highly relevant topic in bioinorganic chemistry. Ruthenium nitroxyl complexes with sufficient robustness towards ligand loss have gained significance as operating platforms to delve into such studies. In this work, we revisit an octahedral {RuNO}(6) complex containing the cyclam-based pentadentate ligand L-py = 1-(pyridine-2-ylmethyl)-1,4,8,11-tetraazacyclotetradecane and explore the thermodynamic and spectroscopic aspects of its reduced states in aqueous media. Upon in situ electro-generation of the bound HNO moiety, we have undertaken different strategies to determine both its acidity and electrochemical properties. This robust HNO complex does not undergo deprotonation in a wide pH range. We have found pK(a) ([Ru(L-py)(HNO)](2+)) = 13.0 +/- 0.1 and . There are indications that pK(a) (HNO) values in several ruthenium-based species correlate with the redox potential associated with the {RuNO}(6,7) and {RuNO}(7,8) couples. The present pK(a) extends the range of acidity of bound HNO to more than five pH units, confirming a remarkable sensitivity to the nature of the coordination sphere. This result lays new foundations to continue rational ligand design that may contribute to a better understanding of the different biological roles of both HNO and NO- by investigating key chemical aspects of model complexes.
But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 120202-71-3, you can contact me at any time and look forward to more communication.
