Abstract
AbstractThree new dinuclear complexes [FeII2(μ‐L)2]X4 (L is the bis‐tridentate ligand 2,5‐bis{[(2‐pyridylmethyl)amino]methyl}‐1,3,4‐oxadiazole and X = ClO4–, BF4– and CF3SO3–) have been synthesized and fully characterized by single‐crystal X‐ray diffraction, Mössbauer spectroscopy and magnetic susceptibility measurements. Upon cooling, a trapped [high‐spin–low‐spin] state of the iron(II) centres is detected. Depending on the counterion, a pronounced thermal hysteresis is found. In one case, it was possible to observe a space group change that accompanies the spin transition. This is the first system showing spin crossover based on an oxadiazole ligand.
