The term <em>oxynitride</em> has long been used in materials chemistry to describe a wide range of compounds containing both oxygen (O²⁻) and nitrogen (N³⁻) anions. However, its precise definition remains ambiguous—whether it denotes a distinct single-phase compound, a mixture of oxide and nitride phases, or simply a doped material. Among various oxynitride synthesis methods, urea-based approaches stand out for their sustainability, cost-effectiveness, simplicity, and relatively low processing temperatures. These methods provide a unique chemical environment for incorporating nitrogen into oxygen-rich frameworks. In this perspective, we revisit the definition and classification of oxynitrides through the lens of urea-mediated synthesis. Issues such as difficulties in nitrogen incorporation, phase control, and the formation of undesirable byproducts are discussed in the context of their potential benefits.
