Özet
A new dialdehyde 1,5-bis(2-formylphenyl)pentane was synthesized from 1,5-dibromopentane with salicylaldehyde and K2CO3; macrocyclic ligand was synthesized by reaction of 2,6-diaminopyridine and 1,5-bis(2-formylphenyl) pentane. Cu(II), Ni(II), Pb(II), Zn(II), Cd(II) and La(III) complexes were synthesized by reaction of the ligand and Cu(ClO4)(2) center dot 6H(2)O, Ni(ClO4)(2) center dot 6H(2)O, Pb(ClO4)(2) center dot 6H(2)O, Zn(ClO4)(2) center dot 6H(2)O, Cd(ClO4)(2) center dot 6H(2)O and La(ClO4)(3) center dot 6H(2)O, respectively. The ligand and its metal complexes have been characterized by elemental analysis, IR, H-1 and C-13 NMR, UV-Vis spectra, magnetic susceptibility, conductivity measurements and mass spectra. All complexes are diamagnetic and Cu(II) complex is binuclear.
