Crystal frameworks that can accommodate a wide range of elements, oxidation states, and stoichiometries are an important component of solid‐state chemistry. These frameworks allow for unique comparisons of different metal‐cation compositions with identical atomic arrangements. The mineral Lyonsite, α‐Cu 3 Fe 4 (VO 4 ) 6 , is emerging as the archetypal framework structure for a large class of materials, similar to known frameworks such as perovskite, garnet, apatite, and spinel. The new lyonsite‐type oxides Li 2.82 Hf 0.795 Mo 3 O 12 and Li 3.35 Ta 0.53 Mo 3 O 12 , in which hafnium and tantalum retain their highest oxidation states, are presented to advance the concept of the lyonsite structure as an adaptable framework.
