Crystal Structures and DNA Binding Properties of 2-Naphthoxyacetic Acid Cu(Ⅱ) Complexes

摘要

Two new copper complexes based on 2-naphthoxyacetic acid ligand,namely [Cu(L)2(CH3CN)]2 (1) and [Cu(L)(1,10-phen)2] (2),where L =2-naphthoxyacetic acid and 1,10-phen =1,10-phenanthroline,were obtained by hydrothermal reaction and characterized by single-crystal X-ray diffraction.The binuclear complex 1 and mononuclear complex 2 belong to space group C2/c and P(1),respectively.The binding properties of the two compounds with ct-DNA were investigated by UV-Vis and fluorescence spectra.The two compounds could bind with ct-DNA through interactions.Compound 2 displays stronger binding ability in the reaction with ct-DNA.
