| 摘 要： | ESR and IR measurements have been carried out for a copper(Ⅱ)complex ofphenolic polymeric crown ether,As a result,the triplet ESR spectrum(S=1)of 3d_z2ground state copper(Ⅱ)ions was first observed for the powder sample.It indicatedthat there existed intramolecular spin-spin interaction betweeen 3d_Z2 groundstate copper(Ⅱ)and copper(Ⅱ)ions.In this binuclear triplet cluster,the axialligntion of one water molecule in a sandwich position to two adjacent copper(Ⅱ)ions was also confirmed by IR spectra,All things considered,a possible structurefor the complex was proposed.
