prismanen.
/ˈprɪzmeɪn/, U.S. /ˈprɪzˌmeɪn/ Chemistry.
1. A red, crystalline hydrocarbon which is an isomer of benzene (C6H6) and has a molecule containing six carbon atoms arranged at the corners of a triangular prism; any of various analogues or substituted derivatives of this.

1964 K. Mislow in Tetrahedron Lett. No. 22. 1418 Prismane or ‘Ladenburg benzene’ (C6H6), which has local Cs symmetry, should have a JC-H of about 180 c.p.s.
1983 F. J. McQuillin & M. S. Baird Alicyclic Chem. (ed. 2) viii. 191 It is therefore easy to understand the thermal stability of prismanes.
2003 Chem. Physics Lett. 380 258 Tetrahedrane and [3]-prismane are some of the smallest highly strained hydrocarbons.
2. A cluster of atoms of iron, sulphur, and/or other elements bonded together in the shape of a prism; spec. one containing six iron and six sulphur atoms. Chiefly attributive.

1984 Jrnl. Chem. Soc. Chem. Communications 356/2 Herein we report on the synthesis and structural characterization of the new [Fe6S6Cl6]3− cluster which contains the hitherto unknown Fe6(μ−S)6]3+ ‘prismane’ cluster.
1993 Proc. National Acad. Sci. U.S.A. 90 1078 Models based on the Fe6S6(L)6n− prismane core, including capped prismanes, satisfy the criterion of a peripheral Mo atom.
2000 Biochemistry 39 15044/1 The name ‘prismane protein’ was abandoned when it became clear..that the HCP [sc. hybrid cluster protein] does not contain the postulated 6Fe cluster.
