tailieunhanh - Metal complexes of π expanded ligands (3): Synthesis and characterization of tris[2-[(octylimino)methyl]-1-pyrenolato-NO] cobalt(III)
The reactions of Co(OAc)2 with two equivalents of 1-hydroxy-2-[(octylimino)methylpyrene L, performed in air, lead to the formation of the cobalt(III) complex, tris[2- [(octylimino)methyl]-1-pyrenolato-N,O] cobalt(III) CoL3, accommodating three chelating pyrenebased salicylaldiminato-type ligands. The complex CoL3 and the referent tris(salicylaldiminato) cobalt(III) 1’(CoIII) were obtained in excellent yields, and their characterisation by 1H NMR, IR, mass spectroscopy, elemental analysis and X-ray diffraction revealed that they were of diamagnetic nature, octahedral geometry with the cobalt centre and meridional configuration. | Metal complexes of π expanded ligands (3): Synthesis and characterization of tris[2-[(octylimino)methyl]-1-pyrenolato-NO] cobalt(III)
