A monovalent aluminum monomer [{HC(CMeNAr) 2 }Al] was obtained by reduction of the corresponding aluminum( III ) diiodide. The molecular structure shows a unique two‐coordinate aluminum center and a planar heterocyclic Al‐N‐C‐C‐C‐N six‐membered ring system (see picture). A nonbonded lone pair of electrons on the Al atom indicates the Lewis base character of the aluminum center. Ar=2,6‐ i Pr 2 C 6 H 3 .
