The given project pursues the following purposes:
1. Experimental substantiation of the stereoatomic model of crystal substance within the framework of which the atoms are modelled by easily deformable spheres or corresponding Voronoi - Dirihlet polyhedra, and the structure of a crystal represents a covering of space.
2. Elaboration of the methods of geometrical and topological crystal-chemistry analysis.
3. Analysis and generalization of crystal structure information using the stereoatomic model of a crystal.
The above list of problems, considered within the project, includes only those of them, on which concrete results (published or in process of publishing) have already been obtained. It assumes further expansion, first of all in the section 'Crystal chemistry of separate classes of compounds'.
Each problem in the list above assumes additional explanation, including:
- General description of a problem;
- Achieved (published) results;
- Developing present and prospective solutions within the given problem.
Due to the large size of the project, the preparation of materials on additional explanation of announced topics and questions will be carried out gradually. For up-to-date information concerning the project, please contact Prof. V. A. Blatov.
We invite all crystal chemists for their cooperation and feedback.
