主　　题：Rare earths Macrocyclic compound Ionic associate Crystal structure 

摘      要：The title compound, (C 34 H 54 N 2O 10 )[Eu(NO 3) 5](C 34 H 52 N 2O 10 =1,2 bis(2,3 benzo 10 aza 15 crown 5 N ethyleneoxy)ethane), was synthesized in acetonitrile solution and its crystal structure was determined by X ray analysis. The crystal crystallizes in monoclinic, space group P21/c with cell parameters a =1 1801(2) nm, b =2 3560(5) nm, c =1 7025(3) nm, β =99 67(3)°, V =4 6662(16) nm 3, Z =4, D c=1 581 g/cm 3. The europium ion is coordinated with ten oxygen atoms from five nitrato groups, and neither O atoms nor N atoms of the macrocyclic compound are bonded to the europium ion.
