A stable tetrazagallole and its radical anion dimer

Chem Commun (Camb). 2021 Sep 14;57(73):9268-9271. doi: 10.1039/d1cc03448k.

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.
