The structures and the electrochemical and spectral properties of a series of discrete [PPh 4 ][MnN(CN) 3 (diimine)] complexes {diimine = 2,2′‐bipyridine [ 1 (bpy)], 4,4′‐dimethyl‐2,2′‐bipyridine [ 1 (4‐dmbpy)], 5,5′‐dimethyl‐2,2′‐bipyridine [ 1 (5‐dmbpy)], 1,10‐phenanthroline [1(phen)] and bipyrimidine [ 1 (bpym)]} have been assessed. These complexes represent potential building blocks for the construction of coordination frameworks. The incorporation of diimine ligands with different π‐accepting capacities allows the systematic tuning of the metal‐to‐ligand charge‐transfer (MLCT) band as well as the Mn V /Mn VI redox potential. The complexes exhibit solvatochromism, and the marked sensitivity of λ max of the MLCT band to polar solvents leads the way towards their potential application in chemical sensing.
