ammine

In coordination chemistry an ammonia ligand is called an ammine. In contrast to alkyl amines it is spelled with a double "m". Cobalt(III) salts frequently actually contain hexaamminecobalt(III) (e.g. cobalt(III) hexammine chloride, [Co(NH3)6]Cl3). Tetraamminedichlorochromium(III) chloride, [Cr(NH3)4Cl2]Cl, has the unique property that the cis isomer is violet and the trans isomer is green. Tetraamminecopper(II), [Cu(NH3)4]2+, is a much deeper blue than the bare copper ion. Formation of the diamminesilver ion, [Ag(NH3)2]+, allows the generally insoluble silver chloride to dissolve in aqueous ammonia.

Noun
1. a complex inorganic compound that contains ammonia molecules
(hypernym) compound, chemical compound

n. ammine

n. amine, metallic substance derived from ammonia (Chemistry)

 Say it 
Compare with amine .A metal ion complex containing ammonia as a ligand . The ammonia nitrogen is bound directly to a metal ion in ammines; amines differ in that the ammonia nitrogen is directly bound to a carbon atom.
