文摘

The room temperature Raman and infrared studies of the tribridged oxo-iron complex (NH₄)₂[{Fe^III₃(μ₃-O)(HCOO)₆}₂{Fe^II(H₂O)₂(HCOO)₆}] (oxoFeFe) were performed and the proposed assignment of the observed vibrational modes has been presented. The studied mixed-valence compound crystallizes in P-1 space group and is constructed from triangular units Fe₃^IIIO and divalent iron ions linked by formate anions. We prove that using the hydrothermal synthesis with a mixture of acetonitrile and propylamine as a solvent can be an alternative method to obtain the oxoFeFe material. The phase purity of the studied crystal is confirmed by its powder XRD pattern.
