Synthesis and Characterization of Mixed Ligand Complexes of Some Lanthanide(III)with N,N'-Triethylenediamine-bis-(3-carboxypropenamide)

摘要

A series of mixed ligand complexes of lanthanide ions with N,N'-triethylenediamine-bis-(3-carboxypropenarnide)have been synthesized and characterized by chemical analysis,conductance,magnetic,thermal and infrared spectral studies.On the basis of the above studies,the following general formula is suggested with a coordination number seven for these complexes:[M(TEBCP)X],where M=Pr(III),Nd(III),Sm(lII),Gd(III)or Dy(III)and X=NO~-_3,Cl~-,C1O~-_4 or SCN~-.
