The cover picture shows a projection of the unit cell of the title compound [Fe(ppo) 3 ] along the c axis. [Fe(ppo) 3 ] crystallizes in the space group $R{\bar 3}$ with two symmetry independent molecules in the unit cell, A and B, situated on a three‐fold axis. In both symmetry independent molecules, the FeO 6 units show distorted octahedral arrangement with a Fe–O(phenolato) bond length of 1.914(2) Å, which is shorter than the Fe–O(carbonyl) distance of 2.070(2) Å. In the unit cell, 12 FeO 6 units, which alternate along the z axis, are involved in crystal packing of [Fe(ppo) 3 ]. The crystal structure is mainly stabilized by C–H···π interactions between phenyl rings of the same layer and by C–H···O(phenolate) interactions between molecules from neighboring layers. More details are discussed in the article by M. Lalia‐Kantouri et al. on p. 2185ff.
