The First Ozonide of a Phosphorus Oxide—Preparation, Characterization, and Structure of P₄O₁₈

Abstract

Communications P 4 O 18 , the first defined binary peroxo compound in the P/O binary system, was obtained by the reaction of ozone with P 4 O 6 . This reaction paves the way to related, hitherto-unknown phosphorus ozonides (yellow circles). Details on the synthesis and properties of P 4 O 18 , the most-oxygen-rich phosphorus compound known to date, are given by M. Meisel et al. on the following pages.

Method for Simultaneous Prediction of Atomic Structure and Stability of Nanoclusters in a Wide Area of Compositions

“…We also distinguish the Si 4 O 18 cluster, which is notably stable by the first criterion. Interestingly, this cluster is similar to the recently synthesized P 4 O 18 cluster but has free-ending O 3 groups instead of closed ones in P 4 O 18 (see Figure d). The important feature of superoxidized clusters is spin-polarized groups with O–O bonds providing their high reactivity, which may determine the toxicity of silica particles. , …”

Hierarchical van der Waals Assemblies to Boost Deep‐Ultraviolet Nonlinear‐Optical Capabilities in Boron Phosphate

“…Phosphinic anhydride (P 4 O 6 ), obtained under limited oxygen conditions, and P 4 O 18 , formed by the reaction of P 4 O 6 with ozone in dichloromethane, are strong candidates. [27] In the absence of P 2 O 5 , the chemical potential stabilization region of 𝛽 1 -2D BPO 4 is shown in Figure 4f, and then we propose a possible reaction equation:…”
