Pearson notation

The use of the so-called Pearson notation (Pearson 1972) is highly recommended (IUPAC, Petzow and Effenberg 1988 etseq, Leigh 1990, Villars etal. 1995) for the construction of a compact symbolic representation of the structure of the phase. As far as possible, it should be completed with a more detailed structural description by using the prototype formula which defines, as previously mentioned, a certain structure type.

This way, the set of the chemical compoimds in the crystalline state can be described by indexing through a combination between the t)q)es of the primitive cell (Table 2.2) of the Bravais networks (Figure 2.30) and of the number n) of atoms (all t)q)es), thus generating the specified so-called Pearson notations (Villars Calvert, 1991), as listed in Table 2.17.
