Abstract:

A new pattern recognition method called hyper-polyhedron model has been proposed for investigating the rules governing the formation of binary complex bromide systems by using the atomic parameters (z/r)_M、X_M'、I_M、I_M'. It has been found that the representative points of binary complex compound-forming systems and those of the systems without binary complex compound are distributed in different regions in the multidimensional space spanned by the atomic parameters. By using hyper-polyhedron method, a hyper-polyhedron model can be obtained to describe the boundaries of the zone where all the binary complex compound-forming samples are distributed. It is proved by means of the hyper-polyhedron model that RbBr-CaBr₂ and CsBr-CaBr₂ are binary complex compound-forming systems.
