nickel tetracarbonyl
Very Low / SpecializedTechnical / Scientific
Definition
Meaning
A chemical compound with the formula Ni(CO)₄, consisting of a nickel atom bonded to four carbon monoxide molecules.
A volatile, toxic organonickel compound, historically significant in metallurgy and industrial catalysis, and a classic example of a metal carbonyl compound.
Linguistics
Semantic Notes
The term is a compound noun used exclusively in chemistry. 'Nickel' refers to the central metal atom; 'tetra-' indicates four; 'carbonyl' denotes the CO ligands. It names a specific molecule, not a class.

Examples
By CEFR Level
- This word is for scientists.
- It is a chemical name.
- Nickel tetracarbonyl is a dangerous chemical.
- Scientists work with nickel tetracarbonyl in labs.
- Due to its high toxicity, nickel tetracarbonyl requires careful handling in fume hoods.
- The Mond process involves the formation and decomposition of nickel tetracarbonyl to purify nickel.

Learning
Memory Aids
Mnemonic
Think of a NICKEL coin surrounded by four fuming car (CARBON) exhaust pipes (monoxide YL).
Conceptual Metaphor
Often conceptualized as a 'poisonous metal heart' (nickel) with four 'toxic tentacles' (CO groups).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Direct calque 'никель тетракарбонил' is correct. Do not translate 'tetra-' as 'четырех' separately from 'карбонил'.
- Avoid using the generic 'карбонил никеля' (nickel carbonyl) when the specific tetra-form is intended.
Common Mistakes
- Incorrect spelling: 'nickle tetracarbonyl', 'nickel tetracarbonyll'.
- Misinterpretation as a common noun or class of compounds rather than one specific entity.

Frequently Asked Questions
No, nickel tetracarbonyl is a synthetic compound produced industrially and in laboratory settings.
It decomposes to release carbon monoxide and nickel particles, both of which are poisonous. Nickel carbonyl is also a potent carcinogen.
Its primary historical use was in the Mond process for purifying nickel metal, though this process has been largely superseded.
Yes, pure nickel tetracarbonyl is a colourless, volatile liquid at room temperature.
