摘 要：<正> Complexes of the general formula,（Me4N）2[(Ln（HDPA）2（DPA）]·Cl,have been synthesized,whereLn=La,Ce,Pr,Nd,Sm and H2DPA=dipicolinic acid.Among them,the crystal structure of the La complexhas been determined by a four-circle X-ray diffractometer to a final R value of 0.080.The crystal isorthorhombic,space group Pccn with a=1.0321（1）,b=1.4951（2）,c=2.0766（6）nm,V=3.2044（9）nm3,andZ=4.The rare earth ion is nine coordinated to forming a tortuous tricapped trigonal prism.
