Abstract

We synthesized a mto (= monothiooxalato)-bridged heterometal complex, Ph₄P[Zn^IIFe^III(mto)₃] consisting of Fe^IIIO₃S₃ and Zn^IIO₆ octahedra and investigated its physical properties. Ph₄P[Zn ^IIFe^III(mto)₃] has a two-dimensional honeycomb network structure. The ESR and ⁵⁷Fe Mössbauer spectra revealed that the rapid spin equilibrium in which the high-spin (HS) state and the low-spin (LS) state exchange in the time scale of 10^-10 < τ < 10^-7 s occurs at the Fe^IIIO₃S₃ site, which is the first report for an assembled metal complex system.
