Abstract

The reaction of the carbazole ligand supported Ga(I) compound LGa(THF) (3) and 1-azido-4-(tert-butyl)benzene (ArN₃) afforded the first stable tetrazagallole LGaN₄Ar₂ (4) bearing a three-coordinate Ga atom. Reduction of 4 with elemental potassium resulted in the radical dimer {[K(18-c-6)]⁺[4]˙⁻}₂, featuring a strong antiferromagnetic interaction between the spin centers.
