Abstract:
An unusual copper(II) complex [Cu(L1a)2Cl2] CH3OH H2O H3O+Cl (1a) was isolated from a solution of a
novel tricopper(II) complex [Cu3(HL1)Cl2]Cl3 2H2O (1) in methanol, where L1a is 3-(2-pyridyl)triazolo
[1,5-a]-pyridine, and characterized with single crystal X-ray diffraction study. The tricopper(II) complex
of potential ligand 1,5-bis(di-2-pyridyl ketone) carbohydrazone (H2L1) was synthesized and physicochemically
characterized, while the formation of the complex 1a was followed by time-dependant monitoring
of the UV–visible spectra, which reveals degradation of ligand backbone as intensity loss of bands
corresponding to O?Cu(II) charge transfer
