Sm <sub>26.25</sub> Ge <sub>22.75</sub> O <sub>5</sub> : Oxidic Sm <sub>30</sub> Ge <sub>4</sub> O <sub>5</sub> Superclusters Embedded in a Zintl Polyanionic Framework
octahedra, coinciding with the experimentally observed oxygen positions. Consistently, DFT calculations show that the incorporation of oxygen lowers the enthalpy of formation in comparison to the hypothetical intermetallic compound. Electronic structure calculations indicate metallic conductivity for both the suboxide and the hypothetical oxygen-free intermetallic compound.
