Cobalt(II) macrocycle complexes based synthesis of Co3O4 nanoparticles: structural and spectral characterization
In this paper, macrocyclic cobalt(II) complexes [CoL1](NO3)2.4H2O (1) and [CoL2](NO3)2.2H2O (2) have been synthesized from the reaction of dialdehydes 1,2-bis(2-formylphenyl)ethane and 1,3-bis(2-formylphenyl)propane, Co(NO3)2.6H2O and 1,2-cyclohexanediamine with molar ration 1:1:1 in methanole and characterized by elemental analyses and FT-IR spectroscopy. Then used as precursors for preparatio...

متن کاملSynthesis and reactivity of cobalt complexes derived from tris(2-pyridylthio)methane ligand: Structural characterization of cobalt(III) complexes containing cobalt–carbon bond
The synthesis, characterization and reactivity of a cobalt(II) complex, [(HL)Co(PyS)](ClO4) (1) (where HL = tris(2-pyridylthio)methane and PyS = monoanionic pyridine-2-thiolate) are discussed. Complex (1) reacts with molecular oxygen to yield a mononuclear low-spin cobalt(III) complex, [(L)Co(PyS)](ClO4) (2). On the other hand, treatment of (1) with a protic acid (pyridinium perchlorate) follow...

متن کاملSelf-assembly of cobalt nanoparticle rings.
Weakly ferromagnetic cobalt nanoparticles can assemble spontaneously into nanosized "bracelets" when dispersed in organic solvents containing resorcinarenes as surfactants. Bracelet self-assembly occurs in solution and is directed by magnetic dipolar interactions, whereas nanoparticle rings with larger diameters are produced by evaporation-driven flow on wetted surfaces.
