Boroarsenates:A Framework Motif and Family Templated on Cations and Anions

摘要

Framework materials have been extensively studied due to their important applications in areas as diverse as cation exchangers,catalysts,and nonlinear optical materials.Oxotetrahedral frameworks are the most prevalent structures,as exemplified by the large number of zeolite,aluminophosphate,and zincophosphate structures.Recently,significant developments of Oxotetrahedral frameworks have been made with the synthesis of a generation of structures containing less common units,for example,BO_4,FeO_4,and NiO_4 tetrahedra;these normally occur in association with the more traditional species of SiO_4,AlO_4,and PO_4.
