The $\mu_{\mathrm{eff}}$ $\left[\mathrm{Fe}(\mathrm{S}_{2}\mathrm{CNEt}_{2})_{3}\right]$ changes with temperature with the involvement of two electronic states. The states are
(a)low spin ${ }^{2} \mathrm{T}_{2 \mathrm{g}}$ and high-spin ${ }^{6} \mathrm{A}_{1 \mathrm{g}}$
(b)low spin ${}^{2}\mathrm{E}_{g}$ and high-spin ${}^{6}\mathrm{A}_{1g}$
(d)low spin ${ }^{2} \mathrm{T}_{2 g}$ and high-spin ${ }^{4} \mathrm{T}_{1 g}$
(c)low spin ${}^{1}\mathrm{A}_{1g}$ and high-spin ${}^{3}\mathrm{T}_{2g}$
