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 Tc of 25.5K has been achieved.[2]
Production[edit]
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]

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
