Five lanthanide complexes containing tacn(1,4,7 triazacyclononane) were synthesized and characterized by elemental analysis, molar conductivity and IR spectra, suggesting that lanthanide metalions are twelve coordinate.

Lanthanide metal cations,La3+,Pr3+,Nd3+,Eu3,Dy3+,Er3+,Tm3+ and Yb3+,reacted with the first ligand,1-Phenyl-3-methyl-4-benzoyl-5-pyrazolone(PMBP)and the second ligand,5-acrylamido-1,10-phenanthroline(5-a-1,10-phen),respectively to form eight lanthanide metal cations——diketone-phenanthroline derivative ternary chelates with the uniform formula Ln(PMBP)3(5-a-1,10-phen).
