摘要：

The samarium iodide/HMPA has been used to promote cyclodimerization of linear a,P-unsaturated ketone. A novel complex [Sm(HMPA)(3)(H2O)(4)](3+)3[I-] (1) was isolated from the reaction and its X-ray crystal structure was determined. The Sm ion is hepta-coordinated displaying a pentagonal bipyramid geometry and an extensive hydrogenbond network which keeps together the molecules in the crystal.
