Abstract
A single crystal of [P(C6H5)(4)][(MnFeIII)-Fe-II(C2O4)(3)] was synthesized and structurally characterized by X-ray; space group is R3c, a = 18.881(2), c = 57.320(10) Angstrom. X-ray diffraction and Mossbauer studies suggested dynamical disorder for the organic cation located on the threefold axis. T he order-disorder phase transition at ca. 330 K is associated with the orie ntational disorder of the P(C6H5)(4)(+) cation occupying a general position in the crystal.
