The entitled compound shows an anomalous temperature dependence of the mean-square amplitude of iron atoms derived from the Lamb-Mössbauer factor near the melting point. To clarify the anomaly, the crystal structure of this compound was determined at room temperature by X-ray diffraction. The crystal is monoclinic with space group P2<SUB>1</SUB>/c, <I>a</I>=20.595(2), <I>b</I>=5.7909(4), <I>c</I>=18.840(2) Å, β=116.870(7)°, <I>U</I>=2004.4(3) Å<SUP>3</SUP>, and <I>Z</I>=8. Weissenberg and oscillation photographs taken at a high temperature lead us to propose a model in which the acetylferrocene molecules rotate around the central iron atoms.
