Abstract: 
Even with simple molecules like C6H6 or C6H5CH3 'gross formulas' like CH or C7H8 are nonsense. In the case of inorganic solids Such procedures are even worse. For example by writing 'K2Si4O9' no hint is given concerning the specific characteristics of the Structure. 'CsFeF3' hides the true composition, which in fact corresponds to (CSCS2Fe2FeF3F6)-C-1-C-2i-Fe-1i-Fe-2-F-1i-F-2i. Therefore, it is essential that the correct formulas have to be added, which are based on point groups (PGr) of particles with exactly the same magnitude of infinitude of the partial lattice (PL). In addition, the connectivity of the PL must be indicated, e.g. [PtCl6]K-2 or K-2[Cl6Pt] instead of K-2[PtCl6]. Therefore, the values of d(X-M), C.P.(X/M), (ECoN)-E-n-(X/M) (with n = 0, 1, n) of the anions have to be added to those of the cations M in the description of crystal structures. The "emancipation' of the anions is urgent, since in most cases their connectivity reigns the utmost important structural features! Sometimes,on-line-formulas' could be used indicating steric arrangements as shown here.
