摘要
ESR and IR measurements have been carried out for a copper(Ⅱ)complex of phenolic polymeric crown ether,As a result,the triplet ESR spectrum(S=1)of 3d_z2 ground state copper(Ⅱ)ions was first observed for the powder sample.It indicated that there existed intramolecular spin-spin interaction betweeen 3d_Z2 ground state copper(Ⅱ)and copper(Ⅱ)ions.In this binuclear triplet cluster,the axial ligntion 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 structure for the complex was proposed.
