Synthesis, Characterization, and Electrochemical Properties of Tri‐ and Tetranuclear CoIII‐Oxo Complexes

European Journal of Inorganic Chemistry, EarlyView.
A series of three tetranuclear and two trinuclear Co(III) carboxylate complexes are synthesized and thoroughly spectroscopically and electrochemically characterized. The relative stability of the tetranuclear versus trinuclear complexes is investigated by density functional theory calculations, and the infrared and ultraviolet/visible spectra are ...

Following the In Situ Pathway of Photoactivated Cyclopentadienone–NHC Iron Complexes as Ammonia–Borane Dehydrocoupling Bifunctional Catalysts

European Journal of Inorganic Chemistry, EarlyView.
Iron complexes bearing cyclopentadienone/hydroxycyclopentadienyl and NHC ligands in combination with carbonyls are active in ammonia–borane dehydrogenation. In situ IR and scale up experiments give insight in the catalytic mechanism. Carbonyl iron complexes, bearing cyclopentadienone/hydroxycyclopentadienyl ligands and N‐heterocyclic carbene as ...

Dinuclear Benzene Linker Bis(pyrazolyl)amine Cobalt(II) Complexes and their Application as Selective Ethylene Dimerization Catalysts

European Journal of Inorganic Chemistry, EarlyView.
Dinuclear (pyrazolyl)amine cobalt(II) complexes are synthesized and structurally characterized. Activation of these cobalt(II) complexes with EtAlCl2 cocatalyst affords highly active and selective ethylene dimerization catalysts. The steric parameters induced by the pyrazolyl substituents largely influence both the catalytic activity and selectivity of

Unveiling Solvent‐Dependent Divergent Hydrogen Production Pathways during the Dehydrogenation of Formic Acid Using N,N′‐Iminopyridine Ruthenium(II) Complexes

European Journal of Inorganic Chemistry, EarlyView.
A readily available, efficient RuII catalyst mediates hydrogen production via formic acid dehydrogenation, via distinct, solvent‐dependent hydrogen production pathways. In water, catalyst robustness is observed, generating turnover numbers (TONs) of 13 791 under stepwise addition, while displaying sustained activity under continuous addition conditions

Hydrothermal Synthesis and Characterization of the Melamine‐Based SHG Material HgCl2(C3N6H6)

European Journal of Inorganic Chemistry, Accepted Article.
The pursuit of efficient nonlinear optical (NLO) materials is critical for advancing optoelectronic applications. This study focuses on the synthesis and characterization of HgCl2(C3N6H6), a melamine‐based hybrid metal halide. Structural analysis reveals a non‐centrosymmetric lattice facilitated by large asymmetric secondary building units and a π ...
