Pressure and Thermally Induced Spin Crossover in a 2D Iron(II) Coordination Polymer {Fe[bipy(ttr)2]}n

2021

Using magnetic measurements and UV -visible spectroscopy we have studied the pressure influence on the spin crossover (SCO) properties of the 2D Fe (II) coordination polymer formulated {Fe[bipy(ttr) 2 ]} n . At variable temperature and fixed pressure, we have measured the magnetic property of this compound. Under different pressures and at room temperature, the visible spectroscopy has been observed. The magnetic experiment displays a two-step spin crossover behavior under pressure. The visible spectroscopic measurements at room temperature show a spin crossover with an asymmetric hysteresis at 0.4GPa.
