Spin‐Crossover and Field‐Induced Single‐Molecule Magnet Behaviour in Metal(II)‐Dipyrazolylpyridine Complexes

The reaction between the 2,6‐di(pyrazol‐1‐yl)‐4‐(bromomethyl)pyridine (L) ligand and divalent transition metal salts led to the formation of three mononuclear complexes of formula [M(L)2](BF4)2·xMeNO2 [M = FeII (1·xMeNO2), x = 0 and 4, M = CoII, x = 2 (2·2MeNO2) and]. Static magnetic measurements hi...
