Luminescent and electrochemical properties of four novel butterfly-shaped hetero-pentanuclear [Zn4Ln] complexes constructed from a bis(salamo)-type ligand

Four novel butterfly-shaped hetero-pentanuclear 3d-4f complexes with a flexible bis(salamo)-type ligand H4L have been synthesized and characterized structurally. The fluorescence spectra of Zn(II)-Ln(III) complexes were investigated and cyclic voltammograms were used to evaluate and present the band energy values of complexes.372
