Solid cobalt(II) cyanide is a coordination polymer consisting of cobalt ions linked by cyanide units in a cubic arrangement, each such cobalt atom having octahedral geometry, and an additional cobalt atom in half of the cubic cavities. [5] That is, the structure is actually Co[Co(CN) 3] 2 in a zeolite-like structure. It forms hydrates and other ...
The New Jersey Zinc Company remained a subsidiary of Horsehead Industries until 1987, when Horsehead merged it with St. Joe Minerals a Missouri lead and zinc producer to form Zinc Corporation of America. The company suffered from worldwide record low prices for zinc in the early 2000s and filed for Chapter 11 bankruptcy in 2002.
In 2019, 552,400 tonnes of zinc, 71 percent of US mined zinc production, and 4.2 percent of world zinc production, came from Teck Resources' Red Dog mine, the world's most productive zinc mine, in northwest Alaska, near Kotzebue. [2] [3] [1] The mine opened in 1989. [4] The zinc is shipped as concentrate to foreign smelters.
Zinc cyanide is the inorganic compound with the formula Zn 2. It is a white solid that is used mainly for electroplating zinc but also has more specialized applications for the synthesis of organic compounds .
Zinc compounds are chemical compounds containing the element zinc which is a member of the group 12 of the periodic table. The oxidation state of zinc in most compounds is the group oxidation state of +2. Zinc may be classified as a post-transition main group element with zinc(II). Zinc compounds are noteworthy for their nondescript appearance ...
Cobalt powder reacts with ammonia to form two kinds of nitrides, Co 2 N and Co 3 N. Cobalt reacts with phosphorus or arsenic to form Co 2 P, CoP, [2] CoP 2, [6] CoAs 2 and other substances. [2] The former three compounds are of interest as catalysts for water electrolysis .

Cyanometallates or cyanometalates are a class of coordination compounds, most often consisting only of cyanide ligands. [1] Most are anions. Cyanide is a highly basic and small ligand, hence it readily saturates the coordination sphere of metal ions.
