Novel vitamin E chelate siderophore derivatives and their VV FeIII complexes have been synthesised the chemical biological properties evaluated. In particular, α- δ-tocopherol with bis-methyldroxylamino triazine (α-tocTHMA) (δ-tocDPA) as well complexes, [V2VO3(α-tocTHMA)2] [V2IVO3(δ-tocTHMA)2], characterised by infrared (IR), nuclear magnetic resonance (NMR), electron paramagnetic (EPR) ultra v...

High-throughput characterization by soft X-ray absorption spectroscopy (XAS) and electrochemical characterization is used to establish a correlation between electronic structure and catalytic activity of oxygen evolution reaction (OER) catalysts. As a model system a quasi-ternary materials library of Ni1-y-zFeyCrzOx was synthesized by combinatorial reactive magnetron sputtering, characterized b...

Species 1-6 are [M(III)(L)2]ClO4 complexes formed with the PhO--CH=N-CH2-Py imines, (L(I))- and (L(tBuI))-, and PhO--CH2-NH-CH2-Py amines, (L(A))- and (L(tBuA))-, in which PhO- is a phenolate ring and Py is a pyridine ring and the prefix tBu indicates the presence of tertiary butyl groups occupying the positions 4 and 6 of the phenol ring. Monometallic species with d5 high-spin iron (1, 2, 3, 4...

A new oxy(ether)tris(amine) macrocycle, MC has been synthesized for CuII complex formation within the cavity of the macrocyclic wheel in endotopic fashion. This complex is further reacted with the bidentate chelating ligands, 1,10-phenanthroline (L1), 2,2′-bipyridyl (L2), 4,4′-dimethyl-2,2′-bipyridyl (L3) and 5,5′-dimethyl-2,2′-bipyridyl (L4) to achieve the pseudorotaxanes PRT1–PRT4, respective...

Bis(benzimidazole)amine-based copper complexes, with structural similarities to the active sites of Lytic Polysaccharide Monooxygenase enzymes (LPMOs), were tested for oxidative degradation cellulose. Spectroscopic characterization as well authentication one them, confirm a tetragonal coordination environment 3 nitrogen donors, thioether in axial positions. Aqueous cellulose was achieved CuII c...

It is demonstrated here that tridentate imine ligands can control the nuclearity of copper(II) complexes based on the donor atoms present in the ligand. The N,N',N''-donating imine ligand led to a mononuclear compound, namely di-chlorido-[N,N-dimethyl-N'-(pyridin-2-yl-methyl-idene)ethane-1,2-di-amine]copper(II) monohydrate, [CuCl2(C10H15N3)]·H2O, 1, while the N,N',O-donating imine ligand produc...
