Nickel arsenide was one of the first compounds that revealed the toxicity of nickel. The damage to the miners' lungs was documented by Georgius Agricola in the 16th century: "kupfer-nickel" ores in the Schneeberg mines contained red-colored NiAs mineral originally mistaken for the copper ore, thus the German: kupfer (copper) in the name. The German: Nickel (demon) name was reflecting the damage it did to the health of the workers,[1] in addition to them being unable to extract any copper from this ore.
The main compound within nickeline, nickel arsenide (NiAs), can be prepared by direct combination of the elements:
Ni(s) + As(s) → NiAs(s)[3]
