The topology of three-dimensional 4-connected nets: Classification of zeolite framework types using coordination sequences

摘要: Abstract Coordination sequences provide a practical numerical scale for expressing the degree of similarity three-dimensional 4-connected nets found in zeolite structures when weighted mean values are used topologically heterogeneous nets. Values coordination limited to 5 terms have been determined nearly all known framework types. They shown be useful classifying frameworks on purely topological grounds and also finding maximum possible space group symmetry more difficult cases.
