Fig. 6: Synthesis and characterization of dicationic organoboron analogue of Thiele’s hydrocarbon.
From: A crystalline radical cation derived from Thiele’s hydrocarbon with redox range beyond 1 V
a Synthesis of 12+, showing contributing resonance structures. b Solid-state structure of 12+[SbF6]2 with side view. For clarity, [SbF6]− counter-anions and H atoms omitted, Dipp groups simplified as wireframes. Thermal ellipsoids set at 50% probability. Key distances (Å): B1−N1 1.495(3), C1’−C2’ 1.495(3), N1−C3 1.367(3), N1−C4 1.374(3), C3−C4’ 1.375(3), C3’−C4 1.375(3), C2’−C4’ 1.374(3), C2’−C3’ 1.367(3).
