Abstract

Design of novel porous compounds is one of the fastest-growing fields of materials chemistry due to the broad range of applications including catalysis, adsorption, and separation. Open-framework germanates have shown large structure diversity and can form structures with extra-large pores. A systematic study of the structural features of the reported germanates is a key for the design of novel porous germanates. In this work, the topological study and classification of all known germanates that are built from Ge₁₀(O, OH)₂₇₋₂₈ (Ge₁₀) or Ge₇(O, OH, F)₁₉ (Ge₇) secondary building units, has been undertaken. We have demonstrated that the combination of topological technique and data mining provides new insights into structural chemistry of a group of compounds. We proposed an efficient and general strategy for prediction of novel structures in germanates and other chemical systems.
