Abstract

Reaction of the organoaluminum hydroxide LAl(Me)OH (1) with different stoichiometric ratios of the homoleptic Sn(II) amide, Sn[N(SiMe(3))(2)](2), produced the bimetallic and trimetallic oxygen bridged aluminum-tin compounds LAl(Me)(mu-O)Sn[N(SiMe(3))(2)] (2) and [LAl(Me)(mu-O)](2)Sn (3), respectively. The former compound exhibits an Al-O-Sn(II)-N core and the latter an Al-O-Sn(II)-O-Al skeleton. In addition, we obtained the [LAl(Me)(mu-O)SnPh(3)] (5) with Al-O-Sn(IV) core by the reaction of [L(Me)Al-O-Mg(THF)(2)N(SiMe(3))(2)] (4) with Ph(3)SnOH in a 1:1 molar ratio.
