Abstract: The centrosymmetric title compound, [(NpO₂)₂(C₇H₄FO₂)₂(C₁₀H₈N₂)₂], contains the dimeric dioxocation (NpO₂⁺)₂ in which two of the four O atoms bridge the Np atoms. Two bidentate chelating-bridging fluorobenzoate anions link the Np atoms of the dimeric cation. The N atoms of the 2,2'-bipyridine ligand occupy two positions in the equatorial plane of the distorted pentagonal bipyramid, forming a five-membered metallacycle.
