Using N2O4 donor symmetric ligand H2L and dca co-ligand, two new isostructural dinuclear CuII–LnIII complexes [Cu(Cl)(L)Ln(NO3)(CH3OH)(H2O)(dca)] [Ln=Ho (1CuHo), Gd (2CuGd)] [H2L = 6,6′-((1E,1′E)-(ethane-1,2-diylbis(azaneylylidene))bis(methaneylylidene))bis(2-methoxyphenol); dca=dicyanamide] were designed, synthesized studied. In the compounds, geometric environment around nine-coordinated Ln(I...

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...

Many efforts in the development of platinum complexes as anticancer drugs have been contemplated in order to reduce the cytotoxicity and to improve the platin drug-resistance.1 Since sulfur-containing compounds such as glutathione and metallothioneins are rich in cells, the formation of the S–Pt bond is generally believed to be one of the major mechanisms in the resistance to cis-platin drugs i...

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...
