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...

Coordination chemistry allows the synthesis of new molecules which show cooperative magnetic phenomena, behaving like magnets. Two main ways of synthesizing these systems have been developed: a) low-dimensional complexes (1-D or 2-D) which are linked in the crystal net and so give ferromagnetic long-range order and b) isolated molecules with high-spin ground state and strong anisotropy, which h...
