“…[12,13,30,31] An exception is T c 2 ȇ, which increases dramatically between x = 0.89 and 0.76. This is a rare observation, which leads to the quick disappearance of the IP with x = 0.76.…”

“…We hypothesize that this is the reason why the crystal structure of the diluted samples (a) to (i) changes at zinc content higher than 0.47, and why mixed single crystals could not be obtained. [26] Dilution studies were achieved on two-step SCO compounds [27] or one-step SCO compound including hysteretic cycles, [17,[28][29][30] but to the best of our knowledge this report is the first metal-dilution study on a two-step SCO Fe II system with two hysteresis loops. For compound 1, cooperativity is mediated mainly by means of intermolecular N-H···S hydrogen-bonding networks.…”

“…The heating and cooling rates were fixed at 10 K min −1 . Temperatures and enthalpies were calibrated over the temperature range of interest (298–400 K) using the solid-liquid transitions of pure In (99.99%) [33], and the crystal-crystal transitions of pure cyclopentane (≥99%) [34], over the range 78–298 K. Scanning electron microscopy (SEM) was performed using a Gemini Digital Scanning Microscope 982 with 1 kV accelerating voltage with an aluminum sample holder.…”
