The title complex C24H38O14Yb2(Mr=896. 62 ) crystallized in orthorhombic system, space group Pbcn with unit cell dimensions a=13. 478 (4), b=16. 161(7), c=15. 110(5); V=3291. 2(2); Z=4; F(000) = 1736; Dc=1. 810g. cm-3;μ= 17. 5 cm-1 (MoKa). The final R and Rw are 0.061 and 0.058 respectively. The title complex is a bridged dimer. The ligands that bridge two Yb(Ⅲ) centerions are the two acetatos in the complex and every Yb(Ⅲ) ion is eight-coordinated, being bonded to one O atom of one H,O molecule, four O atoms of two acetylacetonatos,two O atoms of an acetato and one O atom of another acetato. The coordination polyhedron of the Yb(Ⅲ) ion in the title complex is a dodecahedron.
