NICKELOCENE Usage And Synthesis

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.

Uses

Nickelocene is obtained through reacting nickel halides with sodium cyclopentadienide. It is used as a catalyst or as a complexing agent.

Uses

This metal alkyl may be used to synthesize hybrid organic-inorganic polymeric molecular layer deposition (MLD). Bis(cyclopentadienyl) nickel (Cp 2 Ni) may be used as a Ni precursor for the atomic layer deposition (ALD) of NiO/carbon nanotubes hybrids.

Uses

Catalyst, complexing agent.

General Description

Dark liquid in an 8-10% solution in toluene. Insoluble in water.

Air & Water Reactions

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

Reactivity Profile

Organometallics, such as NICKELOCENE, 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.

Hazard

Toxic by inhalation and skin contact, a carcinogen (OSHA).

Health Hazard

ACUTE/CHRONIC HAZARDS: NICKELOCENE can be absorbed through the skin.

Fire Hazard

NICKELOCENE is flammable.

Safety Profile

Confirmed carcinogen with experimental carcinogenic, neoplastigenic, and tumorigenic data. Poison by intraperitoneal and intramuscular routes. Moderately toxic by ingestion. When heated to decomposition it emits acrid smoke and irritating fumes. See also NICKEL COMPOUNDS.

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.]
