| Abstract: | Four novel rare earth compounds H2LLn(NO3)5H2O](Ln=Pr,Nd,Sm,Eu; L= C26 H38 N2O4 : 1,7,10,16-tetraoxa-4,13-diaza-N, N ′-dibenzyl-cyclooctadecane) were synthesized and characterized by elemental analysis and IR. The crystal structure of C26 H40 N2O4Eu·(NO3)5H2O] was determined by X-ray analysis. The crystal belongs to triclinic, P1 space group with cell dimensions: a =0.9100(4) nm, b =1.3560(3) nm, c =1.6463(4) nm; α =68.62(2)°, β =74.84(3)°, γ =87.50 (2)°; Z =2. The central europium ion is bonded to ten oxygen atoms from the five nitrate groups and one oxygen atom from a water molecule. Coordination number is 11. 1,7,10,16-Tetraoxa-4,13-diaza-N, N ′-dibenzyl cyclo octadecane is not bonded to the europium ion. |
