Abstract

A novel mixed-valence trinuclear heterometal pentafluorobenzoate cluster complex Cr³⁺Fe³⁺Fe²⁺O(C₆F₅COO)₆(C₅H₅N)₃·0.5C₅H₅N·CH₂Cl₂ was synthesized, and its ⁵⁷Fe-Mössbauer spectra were measured with a temperature range of 78 to 298 K. It has been revealed that just one apparent valence state of Fe^2.5+ was observed at room temperature.
