We synthesized a mto (= monothiooxalato)-bridged heterometal complex, Ph4P[ZnIIFeIII(mto)3] consisting of FeIIIO3S3 and ZnIIO6 octahedra and investigated its physical properties. Ph4P[Zn IIFeIII(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 FeIIIO3S3 site, which is the first report for an assembled metal complex system.
