An Odd-Electron Complex [Ruk(NOm)(Qn)(terpy)]2+ with Two Prototypical Non-Innocent Ligands.

{Six combinations of oxidn. states are conceivable for the paramagnetic [Ruk(NOm)(Qn)(terpy)]2+ complex. Single-crystal X-ray diffraction, spectroscopic anal. (IR, EPR at conventional and high frequency), and DFT calcns. establish that it is the iminosemiquinone radical structure that is formed: [Ruk(NOm)(Qn)(terpy)]2+ (k=2+
