Two isostructural, nonclassical Co(H(2)) complexes are prepared from their Co(N(2)) precursors using tris(phosphino)silyl and tris(phosphino)borane ancillary ligands. Comproportionation of CoBr(2) and Co metal in the presence of TPB (tris-(o-diisopropylphophinophenyl)borane) gives (TPB)CoBr (4). One-electron reduction of 4 triggers N(2) binding to give (TPB)Co(N(2)) (2-N(2)) which is isostructural to previously reported [SiP(3)]Co(N(2)) (1-N(2)) ([SiP(3)] = tris-(o-diisopropylphosphinophenyl…

A Dinitrogen Dicopper(I) Complex via a Mixed-Valence Dicopper Hydride.
While DFT studies of mono- and dinuclear copper dinitrogen complexes suggest weak π-backbonding between the d(10) Cu(I) centers and the N2 ligand, they reveal a degree of cooperativity in the dinuclear Cu-N2 -Cu interaction.

Electrocatalytic Proton Reduction by a Cobalt(III) Hydride Complex with Phosphinopyridine PN Ligands.
A catalytic mechanism is proposed in which the pyridine moiety of a PN ligand acts as a pendant proton donor following opening of the chelate ring, especially in the presence of high acid concentration where speciation changes.

The reactivity of an isostructural pair of a neutral S= 1/2 and an anionic S=0 Co-H2 adduct, both supported by a trisphosphine borane ligand (P3B), which serves as a competent precursor for hydrogen atom transfer to t Bu3 ArO⋅ and is a Competent precursor for hydride transfer to BEt3, establishing its remarkable hydricity.


Dinitrogen complexes supported by tris(phosphino)silyl ligands.
Complexes of this type represent the first examples of terminal dinitrogen adducts of monovalent iron, and the ligand architecture allows examination of a unique class of dinitrogensAdducts with a trans-disposed silyl donor.
Synthesis, structure, and electrochemical properties of sterically protected molybdenum trihydride redox pairs: a paramagnetic "stretched" dihydrogen complex?
The decomposition of 2 a(+) by H( 2) substitution with a solvent molecule appears to follow a dissociative pathway in MeCN, and an electrochemical study by cyclic voltammetry provides further evidence for a rapid H(2) elimination process from the 17-electron complexes.
Silylation of iron-bound carbon monoxide affords a terminal Fe carbyne.
Details regarding the electronic structure of the carbyne complex have been explored via the collection of comparative Mössbauer data for all of the complexes featured and also via DFT calculations, which point to a strongly π-accepting Fischer-type car byne ligand that confers stability to a low-valent iron(0) rather than high-valents iron(IV) center.
Molybdenum triamidoamine systems. Reactions involving dihydrogen relevant to catalytic reduction of dinitrogen.
Catalytic runs with MoH( 2) as a catalyst suggest that it is competent for reduction of N(2) with protons and electrons under standard conditions, consistent with dihydrogen being an inhibitor of dinitrogen reduction.
Formation of {[HIPTN(3)N]Mo(III)H}(-) by heterolytic cleavage of H(2) as established by EPR and ENDOR spectroscopy.
The ENDOR pattern of the three equatorial nitrogens is well-reproduced by a model in which the Mo-N(eq) plane has undergone a static, not dynamic, PJT distortion, leading to a range of hyperfine couplings for the three N(eq)'s.
Four-coordinate, trigonal pyramidal Pt(II) and Pd(II) complexes.
It has proven possible to exclude the fifth axial donor to afford the rigorously four-coordinate, trigonal pyramidal (TP) complex {[SiP(3)(iPr)]Pt}(+), and the TP d(8) cations described herein are hence geometrically distinct.
