The first bis(imino)carbazolate pincer ligand supported mononuclear Ga(I) compound LGa: (3) was synthesized and fully characterized. Oxidation of 3 with elemental selenium afforded the dinuclear Ga(III) compound [LGa(μ-Se)] (4) bearing two bridging Se atoms. Ligand substitution of Cr(CO) with 3 under UV light irradiation afforded the gallylene-chromium complex LGa: → Cr(CO) (5). In addition, the attempted synthesis of the aluminium analogue LAl: through reduction of LAlI (7) only led to isolation of the dinuclear Al(III) compound (LAlI) (8), most probably formed through the C-C coupling of two imino radicals.
