Nettet9. jul. 2016 · The sulfoxide isomerization in ruthenium(II) complexes was firstly observed by the group of Keene . In their studies, a color change from yellow to red was observed for the complex [Ru(bpy) 2 (DMSO) 2] + (bpy = 2,2′-bipyridine; DMSO = dimethyl sulfoxide) due to one sulfoxide linkage isomerization upon external stimuli . Nettet1. jan. 1989 · An i.r. study of nitro-nitrito linkage isomerization as well as the ve(N-O) components of ONO- impurities. The absorption peak at 1040 cm- I gradually shifts upwards upon irradiation with u.v. light until an equilibrium value at 1055 cm-I is obtained. This points to a gradual strengthening of the N-O bond during the isomerization process.

Nettet13. feb. 2013 · Only the ampy complex shows no linkage isomerization on the oxidation of Ru, in contrast to the py and isna complex. This indicates that the basicity of the ancillary ligand is reflected in the difference in electrochemical behavior.
