| Abstract: | C12H34O20Eu2,Mr=802.30 triclinic, space group P1, a= 8.955(2), b=9.328(1), c=10.536(2) A,α= 91.74(2),β=113.87(2),γ=118.23(2), V=681.7(2)A,Dm(flotation in CC14/ BrCH2CH2Br)=1.95,DX(Z=1) =1.954g cm-3,λ(MoKα)=0.71069 A,μ=6.41 cm-1,F(OOO)=391.92, T =. 295°K,final RF= 0.032 for 7483 observed reflections with |F0|>3a(|Fo|). The compound is isostructural with the known erbium complex,the basic unit being a centrosymmetric dimer composed of two nine-coordinate polyhedra sharing a common edge. An O atom in one or the three bidentate acetato groups about each europium atom serves as a bridge between the metal centars. The dimeric units are linked by hydrogen bonds involving both ligand and lattice water molecules to form a three-dimensional network. |
