The Dialuminene Ar^iPr8AlAlAr^iPr8 (Ar^iPr8=C₆H-2,6-(C₆H₂-2,4,6-ⁱPr₃)₂-3,5-ⁱPr₂).

ABSTRACT: Careful analysis of the crystals formed in the reduction of Ar^iPr8AlI₂ (Ar^iPr8=C₆H-2,6-(C₆H₂-2,4,6-ⁱPr₃)₂-3,5-ⁱPr₂) with sodium on sodium chloride showed them to contain the long sought-after dialuminene Ar^iPr8AlAlAr^iPr8 (1) that forms alongside the previously characterized alanediyl :AlAr^iPr8. The single crystal X-ray structure of 1 revealed a nearly planar, trans-bent C(ipso)AlAlC(ipso) core with an Al-Al distance of 2.648(2) Å. The molecular and electronic structure of 1 are consistent with an Al-Al double dative interaction augmented with diradical character and stabilized by dispersion interactions.
