From: A crystalline radical cation derived from Thiele’s hydrocarbon with redox range beyond 1 V

a Syntheses of 1 and 2. b Solid-state structure of 2 with side view. For clarity, H atoms are omitted, and Dipp/Mes groups are simplified as wireframes. Thermal ellipsoids set at 50% probability. Key distances (Å): B1−N1 1.424(4), C1−C2 1.356(4), N1−C3 1.415(4), N1−C4 1.413(3), C3−C6 1.325(4), C4−C5 1.334(4), C2−C6 1.460(4), C2−C5 1.447(4). (Mes = 2,4,6-trimethylphenyl).
