Cyclopentadienyl nickel nitrosyl is an organonickel compound with the formula (C5H5)NiNO. It is a diamagnetic, volatile, relatively air-stable red liquid. It has been reported to be the simplest mono-cyclopentadienyl metal complex.[2] It is prepared by treating nickelocene with nitric oxide.[3] Its toxicity is said to be comparable to nickel tetracarbonyl.[2] The complex has C5v symmetry.
The compound reacts with lithium aluminium hydride to give the paramagnetic cluster (C5H5)4Ni4H3.[4]
The related pentamethylcyclopentadienyl complex (C5(CH3)5)NiNO is also known.[5]
Cyclopentadienyl nickel nitrosyl was the subject of several patents as a fuel additive.[6][7][8]
