Phosphorus-nitrogen-oxygen chemistry refers to compounds and materials in which the elements phosphorus (P), nitrogen (N), and oxygen (O) are bonded or arranged in networks. This area is not a single substance but a field that encompasses inorganic, organophosphorus, and materials chemistry where P–N–O motifs are central to structure and reactivity.

A prominent class is phosphazenes and polyphosphazenes, which feature alternating phosphorus and nitrogen in the backbone. These compounds often carry various substituents on phosphorus and can form cyclic or polymeric structures. They are studied for thermal stability, flame retardancy, and versatile processing into coatings and high-performance polymers.

Organophosphorus compounds that contain both P–N and P–O bonds, such as phosphoramidates and related derivatives, also illustrate P–N–O chemistry. These species play roles in catalysis, ligands in coordination chemistry, and, in some contexts, as components of flame retardants and protective coatings. The presence of phosphorus–nitrogen linkages linked to oxygen-bearing groups expands the range of reactivity and functional behavior.

In solid-state and materials chemistry, oxonitride and related phosphorus–nitrogen–oxygen networks are explored for ceramics, glasses, and electronic or ion-conducting materials. While the specific properties depend on composition and structure, common themes include thermal stability, chemical resistance, and the ability to tune conductivity or dielectric behavior through P–N–O connectivity.

Overall, phosphorus-nitrogen-oxygen compounds span a diverse set of substances that leverage P–N and P–O bonding to yield useful traits in polymers, coatings, catalysts, and advanced materials.
