Cyclopentadienyl nickel nitrosyl is a highly toxic organonickel chemical. In its pure form, it is a diamagnetic, volatile, relatively air-stable liquid with a blood-red color. It has been reported to be the simplest mono-cyclopentadienyl metal complex.[2] The chemical was discovered in 1954 by a team at the International Nickel Company.[3] The molecular formula is (C5H5)NiNO. It can be prepared by treating nickelocene with nitric acid.[4] It is extremely toxic (T+), and is considered to be one of the most poisonous organometallic chemicals ever developed. Its toxicity is said to be comparable to nickel tetracarbonyl.[2]

Due to its high toxicity, cyclopentadienyl nickel nitrosyl has very limited usage. It was patented as a fuel additive and anti-caking agent, but it was never used for these purposes due to the health hazards it posed.[2] In the past, it was also studied for its spectroscopic qualities, and saw limited use as a catalyst in organic chemical reactions, but it has since been discounted in favor of less toxic compounds.
