Hello NMR community! I am very happy to share with you our latest work on a family of high spin diruthenium complexes🧲Ligand field and temperature effects on paramagnetic shifts have been explored. And they even form oligomers in high concentrated solutions!🔗 #GlobalnmrTC2022 pic.twitter.com/yN8HYDIO9x

The [Ru2Cl(Dp-FPhF)x(O2CCH3)4-x] series has been synthesized to study the gradual effects of ligand substitution. Regarding this, p-NMR measurements helped us determine paramagnetic effects, which allowed to observe changes in contact and dipolar shifts. Also, variable concentration and temperature experiments provided new insights in the axial reactivity and exchange equilibria, respectively.
