A series of gas-phase reactants is used to treat a Cu-exchanged mordenite zeolite with the aim studying influence reaction environment on formation Cu pairs. The rearrangement ions form multimeric sites as function their oxidation state was probed by X-ray absorption spectroscopy (XAS) and also applying advanced analysis through wavelet transform, method able specifically locate Cu–Cu interacti...

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...

TDMQ chelators have been designed as drug-candidates for the regulation of copper homeostasis and reduction oxidative stress in brain Alzheimer's patients. To achieve suitable biological properties high Cu(II) selectivity a zinc-rich medium, ligands must meet critical coordination chemistry requirements related to structures CuII-TDMQ complexes. The correlation between X-ray diffraction Cu- Zn-...

Use of preformed metal-organic polyhedra (MOPs) as supermolecular building blocks (SBBs) for the synthesis frameworks (MOFs) remains underexplored due to lack robust functionalized MOPs. Herein we report use polycarboxylate cuboctahedral RhII-MOPs constructing highly-connected MOFs. Cuboctahedral MOPs were with carboxylic acid groups on their 12 vertices or 24 edges through coordinative covalen...

The reaction of one equivalent of [n-Bu4N]2[Ni(opboR2)] with two equivalents of [Cu(pmdta)(X)2] afforded the heterotrinuclear CuIINiIICuII containing bis(oxamidato) type complexes [Cu2Ni(opboR2)(pmdta)2]X2 (R = Me, X = NO3- (1); R = Et, X = ClO4- (2); R = n-Pr, X = NO3- (3); opboR2 = o-phenylenebis(NR-substituted oxamidato); pmdta = N,N,N',N",N"-pentamethyldiethylenetriamine). The identities of...
