A Monomeric Aluminum Imide (Iminoalane) with Al-N Triple-Bonding: Bonding Analysis and Dispersion Energy Stabilization.

ABSTRACT: The reaction of :AlAr^iPr8 (Ar^iPr8 = C₆H-2,6-(C₆H₂-2,4,6-ⁱPr₃)₂-3,5-ⁱPr₂) with Ar^Me6N₃ (Ar^Me6 = C₆H₃-2,6-(C₆H₂-2,4,6-Me₃)₂) in hexanes at ambient temperature gave the aluminum imide Ar^iPr8AlNAr^Me6 (1). Its crystal structure displayed short Al-N distances of 1.625(4) and 1.628(3) Å with linear (C-Al-N-C = 180°) or almost linear (C-Al-N = 172.4(2)°; Al-N-C = 172.5(3)°) geometries. DFT calculations confirm linear geometry with an Al-N distance of 1.635 Å. According to energy decomposition analysis, the Al-N bond has three orb
