Cyclopentadienyl nickel nitrosyl

It is a diamagnetic, volatile, relatively air-stable red liquid.

[2] It is prepared by treating nickelocene with nitric oxide.

The compound reacts with lithium aluminium hydride to give the paramagnetic cluster (C5H5)4Ni4H3.

[5] Cyclopentadienyl nickel nitrosyl was the subject of several patents as a fuel additive.
