However, no hysteresis was observed. The magnetic properties of the fully desolvated 38 showed HS nature in the measured temperature range, suggesting that the SCO behavior was highly related to the lattice solvent molecules. 39 showed an abrupt and incomplete SCO without hysteresis with a T1/2 = 245 K. The fully desolvated form of 39 exhibited a gradual and incomplete SCO within 75-200 K temperature range .
