Tetrasupersilyldialuminum [(<i>t</i>-Bu)<sub>3</sub>Si]<sub>2</sub>Al−Al[Si(<i>t</i>-Bu)<sub>3</sub>]<sub>2</sub>: The Dialane(4) with the Longest Al−Al Bond to Date<sup>,</sup>
temperature gave the ruby dialane R*2Al−AlR*2 (1). X-ray structure analysis showed it to contain a Si2Al−AlSi2 skeleton with D2d symmetry and the longest Al−Al bond to date (2.751(2) Å). Water- and air-sensitive 1 reacts with iodine or hydrogen to form R*2AlI or R*2AlH, respectively. Thermolysis and photolysis transform 1, via [R*2Al−AlR*]•, into the tetraalatetrahedrane Al4R*4.
