Abstract: The 1,4,7,10-tetraazadodecane (abbreviatedas cyclen)was synthesized according to the methods of Richman and Atkins,and the 1,4,7,10-tetraazadodecane-α,α',α",α-tetramethyl-1,4,7, 10-tetraacetic acid(abbreviated as DOTMA ) was synthesized by the reactin of cyclone with 2-chloropropanoic acid.The complexes were synthesized by the reaction of DOTMAwith rare earth chloride,and characterized by elementary analysis, thermal analysis and IRspectra.The structure forms of the complexes were expressed as Na [Ln(DOTMA)(H2O)]·2H2O, in which Ln is La, Nd, Er, respectively.

Key words: Rare earth, Polyaza polycarboxylic acid, Complex
