osmiaten.

Brit.

/ˈɒzmɪeɪt/, U.S.

/ˈɑzmiˌeɪt/

Origin: Formed within English, by derivation. Etymons: osmium n., -ate suffix¹.

Etymology: < osmi- (in osmium n.) + -ate suffix¹. Compare slightly later osmiamate n. N.E.D. (1903) gives the pronunciation as (ǫ·smiĕt, ǫ·z-) /ˈɒsmɪət/, /ˈɒzmɪət/.

Chemistry.

A salt or ester of osmic acid; a salt containing oxyanions of osmium in a high valency; (also) spec. (a) = perosmate n.; (b) = osmiamate n. Cf. osmate n.
