Özet

Mononuclear [Co(HL)(2)L'Cl)], [Co(LBF2)(2)L'Cl] or [Cu-((HL)(2)]H2L = {N,N'-bis (4'-N-phenylaza[15]crown-5)di-aminoglyoxime} and a trinuclear, [Cu(L)(2)(CuL')(2)](NO3)(2), complex of the ligand were synthesized and characterized. The mononuclear copper(II) species coordinates to two copper(II) ions through the deprotonated oximate oxygens to yield a trinuclear structure cis-bridged by the oximate groups, with 1,10-phenanthroline as an end-cap ligand. The terminal copper adopts an essentially planar configuration with the nitrogen atoms of H2L. The structure of the ligand and its complexes is proposed and formulated according to the elemental analyses, H-1- and C-13-n.m.r, i.r. and m.s. spectral data.
