The magnetic moment of $\left[\mathrm{Fe}(\mathrm{phen})_{2}(\mathrm{NCS})_{2}\right]$ varies with temperature. The magnetic moments at 200 K and 50 K are 4.9 BM and 0 BM, respectively. Write the d-electron configurations of Fe at both temperatures and give reason for the observed change in the magnetic moment (phen = 1,10-phenanthroline).
