(left) Linear dependency between T_1/2 in the heating (Δ) and cooling () modes versus the anion volume for the series [Fe(NH₂trz)₃]A₂. The circle highlights the case of the nitrate derivative that displays a larger hysteresis width. (right) χ_MT versus T of [Fe(NH₂trz)₃](NO₃)₂ showing a hysteretic ST slightly above the room-temperature region. The nitrate anion is hydrogen-bonded to NH₂trz (in pink) coordinated to two metal centers, thus acting as a supramolecular link in addition to the bridge made by triple N1,N2-1,2,4-triazoles [293].
