Iron oxides are fundamentally important compounds for basic and applied sciences as well as in numerous industrial applications. In this work we report the synthesis and investigation of a new binary iron oxide with the hitherto unknown stoichiometry of Fe 7 O 9 . This new oxide was synthesized at high-pressure high-temperature (HP-HT) conditions, and its black single crystals were successfully recovered at ambient conditions. By means of single crystal X-ray diffraction we determined that Fe 7 O 9  adopts a monoclinic  C2/m  lattice with the most distorted crystal structure among the binary iron oxides known to date. The synthesis of Fe 7 O 9  opens a new portal to exotic iron-rich ( M ,Fe) 7 O 9  oxides with unusual stoichiometry and distorted crystal structures. Moreover, the crystal structure and phase relations of such new iron oxide groups may provide new insight into the cycling of volatiles in the Earth’s interior.
