The ToposPro Topological Collections are intended for topological analysis and classification both of the whole periodic networks and of various types of finite structural units.

With ToposPro Topological Collections you can solve the following tasks of crystal design:

- Determine the type of the overall topology of atomic network. If your network is known you will get its name in a moment!
- Determine the topological types of nanoclusters, polynuclear complex groups, molecules, ligands, or polyhedral zeolite cages. You are wondering if the structural unit you have selected is already known or not? Get the answer immediately!
- Find all examples of crystal structures, where the given topological type was observed. You have synthesized new coordination polymer, metal-organic framework, or metal cluster and want to know if there are any analogs known? Just ask!
- Build distributions of the topological motifs on their occurrence. What topological type is the most abundant? How many diamondoid structures are known? What topological motifs are rare or even empty? All these questions can be answered!
- Find the relations between different topological types, i.e. which topologies can be transformed to each other. Are you interested in the topology that can be obtained from diamond if one unites pairs of nodes of the diamond network to dimeric groups? Do you want to observe the topological routes between diamond and lonsdaleite? You should use the ToposPro Topological Collections!
- Get the information about connection types of ligands in coordination compounds, molecules in molecular crystals, or nanoclusters in intermetallics. What are the possible coordination modes of cyanogroup and which of them is the most preferable? What is the volume of benzene molecule in crystals? What number of hydrogen bonds the hydroquinone molecule usually forms? These are the questions the ToposPro Topological Collections can answer!
