Complexes {[(PTA)2CpRu-μ-CN-1κC:2κ2N-RuCp(PTA)2-ZnCl3]}·2DMSO (13) {[ZnCl2(H2O)]-(PTA-1κP:2κ2N)(PTA)CpRu-μ-CN-1κC:2κ2N-RuCp(PTA)(PTA-1κP:2κ2N)-[ZnCl2(H2O)]}Cl (14), [RuCp(HdmoPTA)(PPh3)(PTA)](CF3SO3)2 (20), [RuCp(HdmoPTA)(HPTA)(PPh3)](CF3SO3)3 (21), and [RuCp(dmoPTA)(PPh3)(PTA)](CF3SO3) (22) were obtained
and characterized, and their crystal structure together with that
of the previously published complex 18 is reported. The
behavior of the 1,3,5-triaza-7-phosphatricyclo[3.3.1.13,7]decane (PTA)
and 3,7-dimethyl-1,3,7-triaza-5-phosphabicyclo[3.3.1]nonane (dmoPTA)
ligands against protonation and κN-coordination
is discussed, on the basis of 15N nuclear magnetic resonance
data collected on 22 different compounds, including PTA (1), HdmoPTA (7H), and some common derivatives as free
ligands (2–6 and 8), along with mono-
and polymetallic complexes containing PTA and/or HdmoPTA (9–22). 15N detection via 1H–15N heteronuclear multiple bond correlation allowed the construction
of a small library of 15N chemical shifts that shed light
on important features regarding κN-coordination
in PTA and its derivatives. To shed light
on the behavior of the triazaphosphines 1,3,5-triaza-7-phosphatricyclo[3.3.1.13,7]decane
(PTA) and 3,7-dimethyl-1,3,7-triaza-5-phosphabicyclo[3.3.1]nonane
(dmoPTA) upon κN coordination and N protonation, the 15N chemical shifts of 22 compounds, including PTA and a representative
variety of its derivatives, piano-stool complexes, were collected
by 1H−15N heteronuclear multiple bond
correlation nuclear magnetic resonance. New heterometallic complexes
containing PTA were also synthesized and fully characterized.

Abstract
Metal-ligand cooperation is an important aspect in earth-abundant metal catalysis. Utilizing ligands as electron reservoirs to supplement the redox chemistry of the metal has resulted in many new exciting discoveries. Here, we demonstrate that iron bipyridine-diimine (BDI) complexes exhibit an extensive electron-transfer series that spans a total of five oxidation states, ranging from the trication [Fe(BDI)]3+ to the monoanion [Fe(BDI]-1. Structural characterization by X-ray crystallography revealed the multifaceted redox noninnocence of the BDI ligand, while spectroscopic (e.g., 57Fe Mössbauer and EPR spectroscopy) and computational studies were employed to elucidate the electronic structure of the isolated complexes, which are further discussed in this report.

Abstract
The splitting of N2 into well‐defined terminal nitride complexes is a key reaction for nitrogen fixation at ambient conditions. In continuation of our previous work on rhenium pincer mediated N2 splitting, nitrogen activation and cleavage upon (electro)chemical reduction of [ReCl2(L2)] {L2 = N(CHCHPtBu2)2–} is reported. The electrochemical characterization of [ReCl2(L2)] and comparison with our previously reported platform [ReCl2(L1)] {L1 = N(CH2CH2PtBu2)2–} provides mechanistic insight to rationalize the dependence of nitride yield on the reductant. Furthermore, the reactivity of N2 derived nitride complex [Re(N)Cl(L2)] with electrophiles is presented.

Abstract
Controlled ligand-based redox-activity and chemical non-innocence are rapidly gaining importance for selective (catalytic) processes. This Concept aims to provide an overview of the progress regarding ligand-to-substrate single-electron transfer as a relatively new mode of operation to exploit ligand-centered reactivity and catalysis based thereon.
