nitridic

Nitridic is an adjective used in inorganic chemistry to describe compounds or species that contain the nitride ion (N3−) or that are based on nitride chemistry. The term is applied to binary and complex nitrides, and to materials or ligands that derive their properties from the presence of nitride units. In solid-state and materials chemistry, nitridic refers to compounds whose anionic framework comprises nitride ions, including binary metal nitrides such as TiN and VN, as well as nitride ceramics like silicon nitride (Si3N4) and aluminum nitride (AlN). The property spectrum ranges from ionic to covalent to metallic bonding, yielding high hardness, high thermal stability, and varying electrical behavior.

In coordination and organometallic chemistry, nitridic often denotes nitrido ligands, N3− or related NR− donors, that bridge metal centers and give nitridic character to clusters and catalysts. The term is also used for materials produced by nitridation, the high-temperature reaction of nitrogen with elements or precursors.

Typical synthesis methods include direct nitridation of metals or metal oxides by nitrogen gas at elevated temperatures, use of ammonia as a nitrogen source, or chemical routes in gas or solid-state synthesis. Nitridic compounds may be air-sensitive and reactive with water, evolving ammonia in hydrolysis.

Applications span hard coatings (TiN, VN), cutting tools, electronic ceramics, and solid-state electrolytes in batteries (e.g., lithium nitride-based systems). Etymology traces to nitride, with the -ic suffix indicating relation.
