dichro-comb. form

Stress is usually determined by a subsequent element and vowels may be reduced accordingly, e.g. dichro-chloride Brit.

/ˌdʌɪkrə(ʊ)ˈklɔːrʌɪd/, U.S.

/ˌdaɪkroʊˈklɔˌraɪd/.

Origin: A variant or alteration of another lexical item; apparently originally modelled on a German lexical item. Etymon: dichroic adj.

Etymology: < dichro- (in dichroic adj.), apparently originally after German dichro- (in Dichrokobaltchlorid ( F. Rose Untersuchungen über ammoniakalische Kobalt-Verbindungen (1871) 43).Formations are found from the second half of the 19th cent.

Chemistry. Now rare.

Forming words denoting substances that display dichroism. Cf. dichroic adj.Chiefly with reference to complex salts of cobalt.

1874 Amer. Jrnl. Sci. 108 191 It is, to say the least, probable that the dichrocobalt-chloride of Fr. Rose, Co₂(NH₃)₆Cl₆) + 2OH₂, represents the corresponding chloride.

1906 Jrnl. Chem. Soc. 90 760 The source of the first-mentioned compound is..obtained from dichloroaquotriamminecobalt chloride (dichro-salt) and sodium hydroxide.

1968 Inorganica Chimica Acta 2 42/1 Another triaquotriammine-cobalt(III) complex, which is derived from the dichro-chloride,..shows much broader spectra.
