A convergent approach for the generation of dendrimers containing the [Ru3O(CH3COO)(6)] electroactive core
(WILEY-V C H VERLAG GMBH, 2008)
We report on a convergent approach for the generation of dendrimers containing the [Ru3O(aC)(6)] electroactive core, of great interest as multielectron transfer catalysts. The proposed strategy is based on the generation ...
Switching nuclearity and Co(II) content through stoichiometry adjustment: {Co II 6 Co III 3 } and {Co II Co 4 III } mixed valent complexes and a study of their magnetic properties
(Royal Society of Chemistry, 2015-02)
We are reporting two new mixed valent Co(ii)/Co(iii) polynuclear complexes, {Co II 6 Co III 3 } and {Co II Co III 4 }, bearing different amount of Co(ii) ions in their cores, through the employment of the multidentate ...
Magnetic Study of a Pentanuclear {Co2IIICo3II} Cluster with a Bent {CoII3} Motif
(Wiley VCH Verlag, 2014-05)
We have synthesised and structurally characterised a new pentanuclear mixed-valent cobalt cluster of formula [CoII3CoIII2(OH)2(piv)6(L)2(H2O)4] (piv = trimethylacetate, H2L = salicylideneanthranillic acid) from reaction ...
Synthesis, characterization and adsorption properties of porous mixed valent diruthenium(II,III)-terephthalate and diruthenium(II,III)-adipate polymers
(ELSEVIER SCIENCE BV, 2008)
Two porous mixed valent diruthenium(II,III)-dicarboxylate compounds have been prepared and characterized by spectroscopic methods, X-ray diffraction and thermogravimetry. Crystalline solids of [Ru(2)(tere)(2)Cl] center dot ...
Cis -2,2′-bipyrimidine-bridged polynuclear complex: A stairway-like mixed-valent {Fe4} cluster
(American Chemical Society, 2010-10)
We report the first example of a polynuclear discrete coordination compound exhibiting only bpym bridges and containing a first-row d transition metal. A smooth self-assembly one-pot synthetic route, starting from simply ...
Synthesis, spectroscopic and electrochemical characterization and molecular structure of polypyridyl ruthenium complexes containing 4,4′-azobis(pyridine)

Structural and spectroscopic evidence of strong electronic delocalization through a cyanido bridge in a mixed-valence Os-Ru complex
(Wiley VCH Verlag, 2010-12)
We report the properties of a trinuclear cyanido-bridged complex, trans-(dmap)4RuII(Âμ-NC)OsIII(CN) 524- [14-; dmap = 4-(dimethylamino)pyridine], whose structure and electronic and vibrational spectra present strong evidence ...
