Abstract:

Two hetero-dinuclear lanthanide(Ⅲ)/Schiff-base complexes {[Ce1.5Sm0.5(clapi)]2}·2CH3CN(1) and {[La1.5Sm0.5(clapi)]2}·2CH3CN(2) were synthesized using template method and characterized by elemental analysis and IR spectra. The structure of complex 1 was determined. Unit cell parameter of complex 1: a=1.067056(2) nm, b=1.14700(3) nm, c=1.38734(3) nm, Z=1, Dc=1.650 Mg/m3, F(000)=740. The two complexes exhibit weak red fluorescence of Sm3+ ions at room temperature, and the experimental results show that inert fluorescence lanthanide ions can influence the fluorescence of the complexes.
