Abstract:
Six combinations of oxidation states are conceivable for the paramagnetic title complex. Single‐crystal X‐ray diffraction, spectroscopic analysis (IR, EPR at conventional and high frequency), and DFT calculations establish that it is the iminosemiquinone radical structure that is formed: Ruk(NOm)(Qn)(terpy)]2+ (k=2+, m=1+, n=1?).
