An alkyne analogue with Al: The first “dialuminyne” of formula Na2[Ar′AlAlAr′] (see picture; Ar′=C6H3-2,6-(C6H3-2,6-iPr2)2) was synthesized and characterized by X-ray crystallography. The structure contains a planar trans-bent C–Al–Al–C array with an AlAl bond length of 2.428(1) Å and a bending angle of 131.71(7)° at Al.
