Two new isotypic d/f-heterometallic purely inorganic cationic materials, [Ag 2 M(Te 2 O 5 ) 2 ]SO 4 (M = Ce IV or Th IV ), were synthesized using the metal oxides (MO 2 and TeO 2 ), silver nitrate, and sulfuric acid under mild hydrothermal conditions. The prepared materials were characterized via single-crystal X-ray diffraction, which revealed that the materials possess a 3D framework of corner-sharing Te 2 O 5 2- units. The tellurite framework creates four unique pores, three of which are occupied by the M IV and Ag I metal centers. The tellurite network, metal coordination, and total charge yield a cationic framework, which is charge-balanced by electrostatically bound sulfate anions residing in the largest of the four framework pores. These materials also possess Ag I in a ligand-imposed linear geometry. |
