Sign in to savethumb|Iceane, colored by symmetry, Carbon in black and blue, hydrogen in white and cyan Iceane is a saturated polycyclic hydrocarbon with formula . It has a cage-like molecular structure, whose carbon skeleton can be viewed as three fused cyclohexane rings in the boat conformation; or as two such rings in the chair conformation, connected by three parallel axial bonds. The spatial arrangement of carbon atoms in iceane is the lonsdalite crystalline structure.

thumb|Iceane, colored by symmetry, Carbon in black and blue, hydrogen in white and cyan Iceane is a saturated polycyclic hydrocarbon with formula . It has a cage-like molecular structure, whose carbon skeleton can be viewed as three fused cyclohexane rings in the boat conformation; or as two such rings in the chair conformation, connected by three parallel axial bonds.

The name "iceane" was proposed by the chemist Louis Fieser about a decade before the compound was first prepared. He was carrying out studies on the arrangement of water molecules in ice, when it occurred to him that there could exist a stable hydrocarbon with the above structure.
