Hazard InformationBack Directory
[General Description]

Dark liquid in an 8-10% solution in toluene. Insoluble in water.
[Reactivity Profile]

Organometallics, such as NICKELOCENE(1271-28-9), are reactive with many other groups. Incompatible with acids and bases. Organometallics are good reducing agents and therefore incompatible with oxidizing agents. Often reactive with water to generate toxic or flammable gases.
[Air & Water Reactions]

Highly flammable. The neat material is sensitive to air. . Insoluble in water.
[Hazard]

Toxic by inhalation and skin contact, a carcinogen (OSHA).
[Health Hazard]

ACUTE/CHRONIC HAZARDS: This chemical can be absorbed through the skin.
[Fire Hazard]

This chemical is flammable.
[Chemical Properties]

GREEN TO DARK GREEN CRYSTALS OR CRYST. POWDER
[Chemical Properties]

Nickelocene is a solid crystalline substance of dark green color, insoluble in water or carbon tetrachloride, slightly soluble in alcohol and liquid ammonia, and readily soluble in nonpolar organic solvents.
[Purification Methods]

Dissolve the complex in Et2O, filter and evaporate in a vacuum. Purify it rapidly by recrystallisation from pet ether using a solid CO2/Me2CO bath, m 171-173o(in an evacuated tube). Also purify it by vacuum sublimation. [Wilkinson et al. J Am Chem Soc 76 1970 1954, Beilstein 16 IV 1831.]
