cyanoplatinite
Very RareTechnical/Scientific
Definition
Meaning
A chemical anion, specifically a complex ion containing platinum and cyanide (Pt(CN)4^2-).
In inorganic chemistry, any salt containing the tetracyanoplatinate(II) anion, often studied for its luminescent and structural properties in coordination chemistry.
Linguistics
Semantic Notes
This term is used exclusively in the domain of inorganic chemistry and coordination chemistry. It refers to a specific anionic complex, not a general concept. The term is formulaic and denotes a precise chemical entity.

Examples
By CEFR Level
- The scientist mentioned a compound called cyanoplatinite in her complex lecture.
- Cyanoplatinite is not a word you will encounter outside a chemistry lab.
- The luminescence of the crystals was attributed to the ordered structure of the cyanoplatinite anions.
- In their synthesis, they precipitated bright yellow barium cyanoplatinite.
Learning
Memory Aids
Mnemonic
Think 'CYAnide + PLATINum + ite (common ending for ions/minerals)' → the 'ite' anion made from cyanide and platinum.
Conceptual Metaphor
Building block metaphor: conceptualised as a stable, square-planar 'building block' or 'unit' used to construct larger crystalline structures.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- May be confused with simpler terms like 'цианид платины' (platinum cyanide), which is less specific. The '-ite' suffix indicates an anionic complex, not a simple salt.
Common Mistakes
- Misspelling as 'cyanoplatinate' (the more common term for the Pt(CN)4^2- ion) or 'cyanoplatinide'.
- Using it as a general term for any platinum-cyanide compound.

FAQ
Frequently Asked Questions
No, it is an extremely rare technical term used only in specialised chemistry.
They are synonyms, both referring to the Pt(CN)4^2- ion. 'Tetracyanoplatinate(II)' is the more systematic IUPAC-style name.
No, it would be highly unusual and not understood outside a specific scientific context.
It functions exclusively as a noun, specifically a countable noun for the chemical ion or its salts (e.g., 'a cyanoplatinite', 'several cyanoplatinites').
