摘 要: | <正> {[Eu(OOCCH2NHCOCH2NH3)2(H2O)2]·(ClO4)3·2H2O}2,Mr = 1572,P21/n,a=12. 014(4),b=8. 910(5),c=22. 749(5)A ,β=91. 73(3)°,V = 2034 A3,Z=2,Dx=2. 15g·cm-3,λ(MoKa) = 0. 71073A,R=0. 060 for 3107 unique observed reflections (I≥3σ(I)). The complex cation is of one-dimensional chain structure in which the basic unit is a dinuclear complex and the gly-gly ligands are coordinated to metal atoms in two kinds of forms. The overall structure of the dinuclear unit is dioxo and dicarboxyl-bridged.
