摘要

Crystal frameworks that can accommodate a wide range of elements,oxidation states,and stoichio-metries 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,alpha-Cu_3Fe_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_3O_(12)and Li_(3.35)Ta_(0.53)Mo_3O_(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.
