Ammine

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. hexaamminecobalt(III) chloride, [Co(NH3)6] Cl3). Dichlorotetraamminechromium(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.
