Chromammine

/ˌkroʊməˈmiːn/ noun

Definition

A variant spelling of chromamamin; a coordination compound of chromium with ammonia ligands used in chemistry and materials science.

Etymology

Alternative form of chromamamin, combining 'chroma' (color) + 'ammine' (ammonia-based ligand). Both spellings emerged from German chemical nomenclature in the late 1800s.

Kelly Says

The 'ammine' spelling actually tells you something important: it means ammonia molecules are bonded directly to the metal, which creates entirely different properties than other chromium compounds.
