Owing to significant ligand disorder in the solid state at 293 K and a phase transformation at low temperature only the atomic connectivity of the compound could be unambiguously determined.2 bcrystallized from hexane in monoclinic space groupP21/n(No. 14) witha=14.3700(17) b=11.4660(11) c=39.054(6) Å β=90.717(10)° V=6434.3(14) Å3;ρcalcd=1.174 g cm−3forZ=8.
Treatment of [Y(AlMe4)3] with 1 equivalent of Et2AlCl produced a fine precipitate and approximately 2 equivalents of AlMe3 formally giving a “Me2YCl” species however1H NMR spectroscopy showed that signals assignable to a “YEt” species were also present.

Compound9 a(C23H60Al3LaO4Si Mr=648.65) crystallizes from hexane in the monoclinic space groupP21/cwitha=10.3104(1) b=17.3973(1) c=19.9956(2) Å β=104.7345(3)° V=3468.72(5) Å3 andρcalcd=1.242 g cm−3forZ=4. Data were collected at 123 K on a Nonius Kappa‐CCD system. The structure was solved by Patterson methods and least‐square refinement of the model based on 6359 (all data) and 5491 reflections (I>2.0σ(I)) converged to a finalwR2=0.0654 andR1=0.0263 respectively. All hydrogen atoms of the methyl groups bonded to aluminum were found in the difference Fourier maps and allowed to refine freely. All of the other hydrogen atoms were placed in calculated positions (riding model). CCDC‐226742 (9 a) contains the supplementary crystallographic data for this paper.

The structure was solved by Patterson methods and least\u2010square refinement of the model based on 6359 (all data) and 5491 reflections (I>2.0\u03c3(I)) converged to a finalwR2=0.0654 andR1=0.0263 respectively. All hydrogen atoms of the methyl groups bonded to aluminum were found in the difference Fourier maps and allowed to refine freely. All of the other hydrogen atoms were placed in calculated positions (riding model). CCDC\u2010226742 (9\u2009a) contains the supplementary crystallographic data for this paper.
