metallocene n.

Brit.

/mᵻˈtalə(ʊ)siːn/

U.S.

/məˈtæləˌsin/

Chemistry any of a group of organometallic compounds that consist of a metal atom bonded between two cyclopentadienyl (or similar aromatic) rings in a sandwich structure, used esp. as catalysts in polymer synthesis; cf. ferrocene n.

ΚΠ

1959 Jrnl. Amer. Chem. Soc. 81 3484/2 Another interesting feature of the relative rates recorded in Table I is the order of effectiveness of metallocene derivatives of Group VIII metals in stabilizing adjacent carbonium ion centers; ferrocene < ruthenocene < osmocene.

1994 M. Bochmann Organometallics II. iv. 53 The presence of ligands other than cyclopentadienyl in a metallocene complex enforces a geometry in which the Cp ligands are no longer co-planar; they adopt a ‘bent sandwich’ structure.
