摘要:

Very recently, five-coordination copper(Ⅰ) complex with distorted square-pyramidal geometry,[CuL1(NCCH3)]+(L1=Dimethyl-2,4-bis(2-pyridinayl)-3,7-diazabicyc lo-[3.3.l]-nonane-9-on-l,5-dicarboxylate)[1], has been synthesized. X-ray structure shows that the rigid ligand L[1] is well suited for copper(Ⅱ) ion, and highly strained for copper(Ⅰ) ion. Those results indicate that the lack of Jahn-Teller effect of copper(Ⅰ) ion often decreases the stability of copper(Ⅰ) precursor complexes, and plays an important in the transportation or activation of dioxygen for copper-containing proteins[1].
