Documented Uses

Used as a catalyst and complexing agent; [Hawley]
Also known as bis(cyclopentadienyl)nickel or NiCp2, this bright green paramagnetic solid is found abundantly in nature in laterite ore minerals, such as limonite, garnierite, and pentlandite. Nickel has a biological role and is found in certain enzymes, including urease, hydrogenase, methylcoenzyme M reductase, and carbon monoxide dehydrogenase.
Nickel is absorbed mainly through the lungs and gastrointestinal tract. Once in the body it enters the bloodstream, where it binds to albumin, L-histidine, and _2-macroglobulin. Nickel tends to accumulate in the lungs, thyroid, kidney, heart, and liver. Absorbed nickel is excreted in the urine, wherease unabsorbed nickel is excreted in the faeces. (L41)
