Abstract
A new low‐temperature phase of ferrocene Fe (C5H5)2, stable below 250 K, has been characterized by means of x‐ray diffraction on powder and differential scanning calorimetry experiments. Lattice of this phase is orthorhombic and its molecular packing is isomorphous to ruthenocence one, so configuration of ferrocene molecules is eclipsed (D 5h symmetry). Experimental conditions to obtain this orthorhombic phase are discussed in connection with crystallite size.Keywords
