Pressure-dependent magnetic susceptibility measurements were carried out on the polycrystalline sample of 1 using the HMD High Pressure Cell. T vs T measurement under ambient pressure showed a stepwise spin crossover (Figure ). As the external pressure increases, the low spin state of 1 stabilizes, leading to a shift in the T1/2 value to a higher temperature for both transitions occurring at ambient pressure conditions. With an applied external pressure of 0.18 GPa, the observed T value is 0.02 cm 3 mol -1 K at 20 K, which suggests the presence of Fe(II) LS at these experimental conditions. With an increase in the temperature at 0.18 GPa, the T value undergoes a stepwise increase in the heating as well as cooling run with T1/2 heating at 189 K and 282 K, and T1/2 cooling at 154 K and 288. Unlike under ambient pressure conditions, the T value recorded as a function of temperature under 0.18 GPa pressure showed thermal hysteresis in both steps of the spin transition. As the externally applied pressure is increased to 0.47 GPa, a further shift in the T1/2 value is observed in both steps, and the thermal hysteresis is preserved. A further increase in the pressure to 0.65 and 0.85 GPa follows the trend of T1/2 shifting to a higher temperature, but only one step of the transition falls in the experimental measurement window.
