non-chembox sections[edit]
2,5,8-Tri-tert-butyl-phenalenyl is a stable phenalenyl radical. It is stable against the formation of σ bonded dimers due to the steric bulk of its tert-butyl groups, but forms face to face π dimers in solid state. Crystals slowly decompose in air. It was the first phenalenyl radical crystallized. [1][2]
