On the compilation of tables for crystal chemical analysis

Abstract

I would like to note not only the diversity seen from these tables, which is important for crystal chemical analysis, but also the importance of the intermediate minimum that is observed for the main numbers. It should be noted that in isotropic complexes, the difference between tetragonaloid and trigonaloid disappears and, in general, crystals could be classified as pseudocubic. But if we add real cubic crystals to them, then we would get a special cluster of crystals for this particular gap, which would be an unfavorable factor for analysis, and it turns out that just in this gap, some rarefaction in distribution naturally results.
