Synthesis of cationic Co‐NBD precursors. L1=Cy2P(CH2)2PCy2, L2=Cy2P(CH2)4PCy2. Solid‐state structure of the cationic portion of [Co(L2)‐NBD][BArF 4]; 15 % displacement ellipsoids, anion and H atoms not shown, −173 °C data collection.34 Approximately octahedral packing of [BArF 4]− anions around a single cation. Surfaces shown at van der Waals radii. Selected bond lengths [Å] and angles [°]: Co–C1 2.212(6), Co–C2 2.110(4), C1–C2 1.394(6), Co–P1 2.2717(8); P‐Co‐P1 103.09(4); ∡CoP1P1′/Co(centC1C2)(centC1′C2′) 28.0(3).
