Meaning and Definition

A compound formed by the coordination of ammonia (NH₃) or an amine with a metal ion.

In coordination chemistry, a specific type of ligand complex where ammonia or an amine is directly bonded to a central metal atom via the nitrogen's lone pair of electrons. It is a subclass of coordination compounds.

  • Incorrect pluralisation (ammines, not ammineses).

FAQ

Frequently Asked Questions

An 'amine' is an organic compound derived from ammonia by replacing one or more hydrogen atoms with organic groups (e.g., methylamine, CH₃NH₂). An 'ammine' is an inorganic coordination compound where ammonia (NH₃) itself is bonded as a ligand to a metal ion.

No, it is a very low-frequency, highly technical term used almost exclusively in the field of inorganic chemistry.

In technical jargon, it can be used verbally to describe the process of forming an ammine complex (e.g., 'to ammine a metal salt'), but this usage is rare and confined to specialist literature.

In British English, it is typically /ˈæmiːn/ (AM-een). In American English, both /ˈæmin/ (AM-in) and /əˈmin/ (uh-MEEN) are acceptable, with the former being more common.

A compound formed by the coordination of ammonia (NH₃) or an amine with a metal ion.

Ammine is usually technical/scientific in register.

Learning

Memory Aids

Mnemonic

Think 'AMMonIa' + 'mINE' (as in, a metal mine). An AMMINE is where ammonia is 'mined' or bound to a metal.

Conceptual Metaphor

A HOST-GUEST relationship. The metal ion is the host, and the ammonia molecule is a guest that donates its lone pair to form a bond.
