Nickeline or Niccolite

A mineral consisting of nickel arsenide (NiAs) containing 43.9% nickel and 56.1% arsenic.

Small quantities of sulfur, iron and cobalt are usually present, and sometimes the arsenic is largely replaced by antimony. This last forms an isomorphous series with breithauptite (nickel antimonide).

The main compound within nickeline, nickel arsenide (NiAs), can be prepared by direct combination of the elements:
Ni(s) + As(s) → NiAs(s)

The unit cell of nickeline is used as the prototype of a class of solids with similar crystal structures. Compounds adopting the NiAs structure are generally the chalcogenides, arsenides, antimonides and bismuthides of transition metals.

The following are the members of the nickeline group:

Achavalite: FeSe

Breithauptite: NiSb

Freboldite: CoSe

Kotulskite: Pd(Te,Bi)

Langistite: (Co,Ni)As

Nickeline: NiAs

Sobolevskite: Pd(Bi,Te)

Sudburyite: (Pd,Ni)Sb
