N2 - Heteronuclear nickel(II)-lanthanide(III) complexes, NiLn(dhbaen)(NO3)(H2O)2 (Ln = La, Eu or Gd), and a mononuclear Eu(III) complex, Eu(Hdhbaen)(H2O)3, were synthesized, where H4dhbaen denotes N,N′-bis(3-hydroxysalicylidene) ethylenediamine. IR spectra shows that Ni(II) and Ln(III) ions are located at the endogenous N2O2- and exogenous O4-coordination sites of ligand, respectively. Based on CD spectra, it was concluded that amino alcohols are specifically bound at the Ni(II)-Ln(III) heterometal centre, through the nitrogen to the Ni-site and through the oxygen to the Ln-site. The fluorescence intensity of the mononuclear Eu(III) complex is much greater than that of the heteronuclear Ni(II)-Eu(III) complex.
