Abstract

An unusual copper(II) complex [Cu(L ^1a ) ₂ Cl ₂ ] CH ₃ OH·H ₂ O·H ₃ O ⁺ Cl ⁻ ( 1a ) was isolated from a solution of a novel tricopper(II) complex [Cu ₃ (HL ¹ )Cl ₂ ]Cl ₃ ·2H ₂ O ( 1 ) in methanol, where L ^1a 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 (H ₂ L ¹ ) was synthesized and physico-chemically 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.
