Abstract
The total and the partial valence electron concentrations(VEC), two variables which can be easily calculated from the composition of the compound and the valence electron numbers of the participating atoms, serve as useful parameters to predict probable structural features of compounds with a tetrahedral structure or a tetrahedral anion partial structure such as an anionic tetrahedron complex. The structural features to be predicted are the average number of nonbonding orbitals, the number of atoms in molecular structures, the average number of anion-anion bonds per anion or the average number of electrons which remain with the cation to be used either for cation-cation bonds or nonbonding orbitals.
