Tetrahedral structures, lanthanide-coordination

The second half of the lanthanide series react with the more bulky BuLi reagent to form tetrahedrally coordinated complexes, such as [Li(TMEDA)2]+[Lu( Bu)4]-. Figure 18.4.6(c) shows the structure of the anion [Lu(fBu)4]-. [Pg.699]

In the examples discussed above, the transition metals are heteroatoms that occupy tetrahedral sites within the framework. There are also examples where transition metals occupy octahedral framework sites within a porous silicate framework. In the much studied titanosilicate ETS-10, in which the structure contains a mixture of octahedral titanium and tetrahedral silicon, a small fraction of the octahedral titanium may be reduced to Ti(III) by hydrogen. In addition, it is possible to include the lanthanide cerium into the mixed coordination microporous silicate AV-5. As described in Section 2.5.1, this... [Pg.248]
