The cyclic alumosiloxane [{LAl(渭-O)(Ph2Si)(渭-O)}2] (3) and alumosilicate [{LAl(渭-O){(tBuO)2Si}(渭-O)}2] (4) were obtained by reaction of the appropriate R2Si(OH)2 precursor (R = Ph, OtBu) with [{LAl(H)}2(渭-O)] (1), providing a nice illustration of the Loewenstein rule at work at the molecular level.
