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 ...
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 .
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 .
KOCN is prepared by heating urea with potassium carbonate at 400 °C: . 2 OC(NH 2) 2 + K 2 CO 3 → 2 KOCN + (NH 4) 2 CO 3. The reaction produces a liquid. Intermediates and impurities include biuret, cyanuric acid, and potassium allophanate (KO 2 CNHC(O)NH 2), as well as unreacted starting urea, but these species are unstable at 400 °C.
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 ...
Eagle Mine is an abandoned mine near the ghost town of Gilman and about one mile southeast of Minturn, in the U.S. state of Colorado. [1]Mining began in the 1880s, initially for gold and silver but focusing predominantly on zinc during later stages of its operation.
These structures cause zinc to have two bonding d-orbitals and three low-lying non-bonding d-orbitals (see non-bonding orbital), which are available for binding. When zinc lacks electron donating ligands it is unable to obtain coordination saturation, which is a consequence of the large atomic radius and low electron deficiency of zinc.
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.
