Prolonged storage of solutions in the Al(OPri)(3)-Ta(OPri)(5)-(PrOH)-Pr-i system containing additional (PrOH)-Pr-n leads to crystallization with minor yields of a new aluminium. oxopropoxide, Al11O6(OPrn)(10)(OPri)(10)(OR)(ROH)(2) (R=Pr-i, Pr-n) (1). Interaction of Al(OPri)(3) with Mg(acac)(2) (in a 1:1 ratio) in toluene on refluxing leads to formation of Al5Mg4O3(OH)(3)(OPri)(8)(acac)(6).0.5PhMe (2) in minor yields. Both molecules contain two pentanuclear cores [M-5(mu(4)-O)(mu3-O)(mu-OX)(6)(Y)(4)] (X = H, Pr-n, Y = OPri, acac/2) and differ only in the manner in which they are attached to each other, i.e., via the central [Al(mu(3)-O)(2)(mu-O)(2)(OR)] unit in 1, and via a common [Al-(mu(3)-O)] edge and an, additional (mu-OH)-group in 2. The core structures in the molecules of aluminium and iron oxoalkoxides are discussed. (C) 2003 Elsevier Ltd. All rights reserved.
