Synthesis and crystal structures of [Ph3C]21 and 2 (ellipsoids are drawn at the 35 % probability level except for the C6F5 units that are depicted as wire frame model, disordered cocrystallized dichloromethane in [Ph3C]21. 2(CH2Cl2) was taken into account using the SQUEEZE routine as implemented in the Platon program, 17 one of the [Ph3C]+ cations and disorder in the B2(CN)6 units and in some of the C6F5 units in 2 is omitted for clarity) and a table with selected bond length (calculated values in parentheses, for details see SI) of II, 1, and 2 ([a](N2H6)+ salt; [b][Ph3C]+ salt; [c]main part of three-fold disorder).
