The asymmetric unit of the title compound, 2C(7)H(2)F(4)O(2)·C(10)H(8)N(2), contains one mol-ecule of 2,3,4,5-tetra-fluoro-benzoic acid (tfb) and half of a centrosymmetric 4,4'-bipyridine mol-ecule. Inter-molecular O-H⋯N hydrogen bonds link two tfb mol-ecules and one 4,4'-bipyridine mol-ecule into a trimer. Weak inter-molecular C-H⋯F inter-actions assemble these trimers into a three-dimensional network structure.
