Acepentalene is a tricyclic anti-aromatic compound. Its molecular formula is C₁₀H₆. It consists of three five-membered rings fused across three of the five carbon atoms. The central carbon atom in acepentalene is part of all three rings. There are formally five double bonds in acepentalene, so that the molecule formally contains four double bonds on the exterior, and one double bond from the central carbon to the exterior of the ring system.

The acepentalene dianion, which can be stabilized by two lithium atoms, is more stable. The radical anion is also known.^[1]
