SYNTHESIS AND CRYSTAL STRUCTURE OF A FOUR-COORDINATE ARYLOXO SAMARIUM COMPLEX [SM(OAR)(3)(THF)](THF) (OAR=2.6-DITERTBUTYL-4-METHYLPHENOXO)

摘要

The aryloxo samarium complex [Sm(ArO)(3)(THF)](THF) has been prepared by the reaction of SmCl3 with 3 equiv. of NaOAr in THF. An X-ray crystallographic analysis shows the complex to be a four-coordinate aryloxide complex. Three oxygen atoms of aryloxo and one oxygen atom of THF coordinate to the samarium to form a distorted tetrahedron. The average Sm-O(Ar) distance is 2.151(7) Angstrom. [References: 10]
