Unusual coordination mode of tetradentate Schiff base cobalt(III) complexes.
Contrary to the stereotype, Jacobsen's catalyst, chiral (salcy)Co(III)OAc adopts an unusual binding mode. The tetradentate {ONNO} ligand does not form a square plane but wraps cobalt in a cis-β fashion while acetate is chelating.
متن کاملCatalyzed Schiff Base synthesis over Bifunctinalized Cobalt/Zinc-Incorporated Mesoporous Silica Nanoparticles under UV irradiation
A novel series of the Co/Zn-MSN catalysts with Si/Zn molar ratio of 10 and 1, 3, 5 and 7 wt% Cobalt (denoted by CZ-X-MSN) were synthesized using post-synthesis methods. The samples were characterized by XRD, SEM, FTIR, TEM and nitrogen sorption methods. With a constant Si/Zn ratio, the increase of cobalt species from 1 to 7 wt% led to decrease the catalysts surface area from 408 m2g-1 for CZ-1-...
متن کاملNovel nanohybrids of cobalt(III) Schiff base complexes and clay: synthesis and structural determinations.
The [Co(Me(2)Salen)(PBu(3))(OH(2))]BF4 and [Co(Me(2)Salen)(PPh(3))(Solv)]BF(4), complexes were synthesized and characterized by FT-IR, UV-Vis, (1)H NMR spectroscopy and elemental analysis techniques. The coordination geometry of [Co(Me(2)Salen)(PPh(3))(H(2)O)]BF(4) was determined by X-ray crystallography. It has been found that the complex is containing [Co(Me(2)Salen)(PPh(3))(H(2)O)]BF(4) and ...
متن کاملThe synthesis, characterization and catecholase activity of dinuclear cobalt(ii/iii) complexes of an O-donor rich Schiff base ligand
Three dinuclear Co complexes [(Co2(H2L)2(OAc)2)] CH3OH (1), [CoCo(H2L)2(OAc)] 2CH3OH H2O (2), and [CoCo(H2L)2(CH3CN)(H2O)]Cl CH3CN 4H2O (3) [H4L is (3,5-di-tert-butyl-2-hydroxybenzylideneamino)-2(hydroxymethyl)propane-1,3-diol] were synthesized and characterized using single crystal X-ray diffraction and other analytical methods. Complex 1 having two Co centres was the only one found to show ca...
متن کاملSynthesis and Crystal Structure of Cobalt(III) Complexes of Salen Type Schiff Bases and Tertiary Phosphanes as Ligands
The new [Co(Salen)(PBu3)2]ClO4, [Co(Salen)(PBu3)2]BF4, [Co(Salpn)(PBu3)2]ClO4 and [Co(Salen)(PMe2Ph)2]ClO4 ( where salen = bis(salisylaldehyde)ethylenediimine)) complexes were synthesiszed and chracterized by IR, UV-Vis, 1H NMR spectroscopy and elemental analysis. The IR and 1H NMR spectra cofirmed that the synthesised complexes contain Schiff base ligand, phosphane and conter ion and the eleme...
