Synthesis and structure of alkali metal 'ate' complexes in the yttrium/2,6-dimethylphenoxide system

The neutral complex Y(OAr)3(THF)3, 1, (Ar=C6H3Me2-2,6) prepared from Y[N(SiMe3)2]3 and HOAr, can be converted to the ionic 'ate' salts [(DME)Li]2[(μ-OAr)4Y(OAr)], 2, [(THF)3K][(μ-OAr)2Y(OAr)2(THF)2], 3, and [Na(THF)6][(C5Me5)Y(OAr)3], 4, with the alkali metal reagents LiOAr, KOAr, and NaC5Me5 (DME=dimethoxyethane). The yttrium center in complex 2 is square pyramidal with the terminal aryloxide ligand in the apical position and no agostic interactions. The octahedral coordination environment around yttrium in 3 is formed by two bridging aryloxides, two terminal aryloxides and two THF molecules. This complex has close K-C(ipso) contacts of 3.288(9) and 3.400(10) A. Complex 4 contains an isolated hexasolvated cation and a formally 6-coordinate yttrium atom in which the three aryloxide oxygen atoms and the η5-C5Me5 ring centroid describe a distorted tetrahedron.
