ferrocenen.

Brit.

/ˈfɛrəsiːn/, U.S.

/ˈfɛrəˌsin/

Origin: Formed within English, by compounding. Etymons: ferro- comb. form, cyclopentadiene n.

Etymology: < ferro- comb. form + c- + -ene (both in cyclopentadiene n.).

Chemistry.

An orange crystalline iron compound whose molecule consists of an iron atom symmetrically situated between two parallel, superimposed cyclopentadienyl rings.Systematic name: dicyclopentadienyl iron; Fe(C₅H₅)₂.

1952 R. B. Woodward et al. in Jrnl. Amer. Chem. Soc. 74 3458 We now wish to record experiments which demonstrate typically aromatic properties of this unique iron compound, for which we propose the name ferrocene.

1957 Jrnl. Chem. Educ. 34 271/1 Ferrocene has demonstrated significant antiknock properties in fuels for spark ignition engines.

1996 M. J. Winter d-Block Chem. (1998) ii. 16 Ferrocene and dibenzene chromium are examples of ‘sandwich’ complexes, the metal ion being ‘sandwiched’ between two planar cyclic molecules.

2007 Sydney Morning Herald (Nexis) 8 Aug. 1 The International Organisation for Standardisation..recommends ferrocene not be used in fuel as it causes iron deposits to build up on spark plugs.
