Predictions for possible new, doubly and triply bridged oxides and peroxides of C, N, P, and S

Abstract

By regarding the X^2–,3– oxoanions of main group elements as pseudochalcogenides or pseudopnicogenides, and possibly cutting the peroxide bridges to oxide bridges, one arrives at a series of so far experimentally unknown oxides and peroxides, X₂, having high, but not exceedingly high energies.
