Meaning and Definition
A chemical compound formed when a central metal ion is bonded to one or more ligands, typically resulting in a charged coordination complex.
In chemistry, a salt that contains a complex ion, where a metal atom or ion is attached to other molecules or ions (ligands) through coordinate covalent bonds. It is distinct from a simple salt like sodium chloride.
Dialectal Variation
British vs American Usage
Differences
No significant lexical differences. Both use the same term. Spelling conventions for related words (e.g., 'colour' vs. 'color') do not apply to this specific compound noun.
Connotations
Purely technical and neutral in both varieties.
Frequency
Used with identical frequency in academic and technical chemistry contexts in both regions. Virtually unused outside these contexts.

Common Mistakes When Using “complex salt”
- Using 'complex' as an adjective describing a 'complicated salt' rather than as part of the technical noun phrase.
- Confusing it with 'double salt'.
- Incorrect stress: stressing 'complex' as in 'complex problem' (/kəmˈpleks/) instead of the noun/adjective form (/ˈkɒm.pleks/).
FAQ
Frequently Asked Questions
No. A double salt (e.g., alum) dissociates into its simple ions in water. A complex salt dissociates to yield a stable complex ion that remains largely intact in solution.
No. In this scientific noun phrase, 'complex' is stressed on the first syllable (/ˈkɒm.pleks/), as in 'apartment complex'. The second-syllable stress (/kəmˈpleks/) is for the adjective meaning 'complicated'.
Almost never. It is a highly specialised technical term specific to inorganic and coordination chemistry.
Potassium ferrocyanide, K4[Fe(CN)6], is a classic example. The [Fe(CN)6]4- ion is the stable complex ion that does not readily release Fe2+ or CN- ions.
A chemical compound formed when a central metal ion is bonded to one or more ligands, typically resulting in a charged coordination complex.
