Abstract
A new class of compounds, called "periodic compounds," identified by the selection rule G = Σdiei/Σdi, where G assumes the integral values 1, 2, 3, . . . corresponding to the periodic table groups I, II, III, . . ., is discussed. The number of bonding electrons contributed by an atom of kind i is designated ei, and di gives the number, per formula weight, of atoms of this kind. Both ei and di assume integral values. Periodic compounds consist of symmetrical and unsymmetrical types. The recent synthesis of the unsymmetrical periodic compound B2O, an isoelectronic analog of carbon, suggests that many more unsymmetrical types may be amenable to synthesis, particularly by high-pressure and high-temperature techniques.Keywords
