What is it about?
For the first time, a method for calculating formulas of homologous series of chemical compounds of the systems (Aa+ – Bb+ – Cc–) and {Zn2+ – Ge4+ – P3–} in a generalized form is presented. The calculation is confirmed by the literature experimentally obtained compounds: thirteen compounds of the system (Na+ – Ti4+ – O2–), seven – systems (Li+ – Ti4+ – O2–), five – systems (K+ – V5+ – – O2–), eight – systems (Ba2+ – Cu2+ – O2–). Homological series in (Aa+ – Bb+ – Cc–) have the following generalized form: A{t – k·r + nr – r)bcBracC{t – k·r + nr)ab and AtbcB{r – k·t + nt – t}acC (r – k·t + nt)ab.

Why is it important?
In (Zn2+ – Ge4+ – P3–) systems for the m-group the formulas of homologous series, that develops towards Ge3P4, have the following generalized form: Zn6tGe(6r – 6kt + 6n – 6t)P(8r – 8kt + 8n) and for am-homologous series – Zn6Ge3nP4(n + 1). A method for calculating formulas of homologous series of chemical compounds in a generalized form can be used for any system of chemical elements.
Perspectives
The search for new Chemical Compounds (CC) in multicomponent systems of Chemical Elements (CE) is a difficult task. The great variety of properties of a set of Three-Component Chemical Compounds (TCC) is of great interest in solving a number of scientific and applied studies. There are known works in the literature that use the mathematical apparatus for predicting phases in multicomponent systems. Thus, semiempirical quantum-chemical methods, such as Hartree-Fock-Rutaan and Hartree-Fock-Slater methods are used to calculate the formulae of hypothetical multicomponent CC. When using these methods to describe a chemical system, many physical and chemical phenomena must be taken into account. The exact solution of the basic laws leads to overcomplicated calculations. Therefore, for practically all CE systems, the solution of the corresponding electronic equations used in quantum-chemical calculations is only possible approximately.
