Photolysis of nitrosylruthernium chloro complexes

Photoactive ruthenium nitrosyls: Effects of light and potential application as NO donors

“…In 1971, Cox and Wallace observed that an acidic aqueous solution of potassium pentachloronitrosylruthenate(III) ( 1 ) turned brown over a period of hours when exposed to light, yet was thermally stable under dark conditions [100]. Controlled experiments confirmed that when an aqueous solution of 1 was exposed to UV light, the aqua complex [Ru III (H 2 O)(Cl) 5 ] 2− was formed (Fig.…”

“…The earliest accounts of photoactive ruthenium nitrosyls indicate the photosensitivity of the {Ru-NO} 6 moiety [100]. Various ruthenium nitrosyls with chlorides as additional ligands have been studied.…”

Ab initio molecular dynamics simulation of aqueous solution of nitric oxide in different formal oxidation states

“…However, in the photolysis of {Ru-NO} 6 complexes NO is released as NO • . For instance, pentachloronitrosylruthenate(II), [Ru(Cl) 5 (NO)] 2− , when exposed to UV light generates Ru(III) and NO • [29], as was demonstrated by IR [30], EPR [31] experiments. In addition to the NO + and NO • that can be released by transition metal nitrosyl complexes, NO can also exists in the form of NO − , for instance through a biological http://dx.doi.org/10.1016/j.cplett.2015.08.020 0009-2614/© 2015 Elsevier B.V.

Nature of the bond, reduction potential, and solvation properties of ruthenium nitrosyl complexes of the type trans‐[Ru(NH3)4(L)(NO)]2+/3+ and [Ru(salen)(L)(NO)]2+/3+ in different charge and spin states

“…[ 35–39 ] In fact, experimental results shows that the nitrosyl can be released as NO + , NO • , and NO − . [ 36–43 ] Some of this species can also be involved in the formation of HNO, which has several implications in biology. [ 44,45 ] Therefore, the study of the reactivity of this NO species in solution is of fundamental importance to understand the nature and fate of these released species.…”
