On a plane : Addition of PhCCH to Ar′GaGaAr′ (Ar′=2,6‐(2,6‐ i Pr 2 C 6 H 3 ) 2 C 6 H 3 ) yielded the 1,4‐digallacyclohexadiene [{Ar′GaC(Ph)CH} 2 ] ( 1 ), which afforded the 1,4‐digallatabenzene dianion [Ar′GaC(Ph)CH] 2 2− ( 2 ) upon reduction with potassium (see scheme; C gray, Ga green, K blue). Structural parameters, DFT calculations, and 1 H NMR spectroscopy support aromatic character of 2 .
