a Synthesis of RN3 pyridinophane ligands. b Synthesis of (RN3)NiCl2 complexes (1a and 1b) and c ORTEP representation of the 1a obtained by X-ray diffraction (ellipsoids are shown at 50% probability and the hydrogen atoms omitted for clarity). Selected bond lengths (Å): Ni–Npy 2.058, Ni–Namine 2.056, Ni–Cl 2.322. d Space-filling model of 1a highlighting the steric protection of the Ni center by the H atoms of the ethylene bridge.
