Nitride chloride

A chloride nitride is a mixed anion compound containing both chloride (Cl⁻) and nitride ions (N³⁻). Another name is metallochloronitrides. They are a subclass of halide nitrides or pnictide halides.^[1]

The group 4 element chloride nitrides can be intercalated by alkali metals that supply extra electrons, and other molecules such as from solvents like tetrahydrofuran, yielding layered substances that are superconductors. A superconductor transition temperature T_c of 25.5K has been achieved.^[2]

Production

Nitride chlorides may be produced by heating metal nitrides with metal chlorides. The ammonolysis process heats a metal chloride with ammonia.^[3] A related method heats a metal or metal hydride with ammonium chloride. The nitrogen source could also be an azide or an amide.^[3]
