In the title compound, {[Cu(C8F4O4)(CH3OH)]·CH3OH}n, two CuII atoms are bridged by four carboxyl­ate groups, forming the well known paddle-wheel secondary building unit (SBU) with axial methanol ligands. In each ligand, the dihedral angles between the benzene ring and the two carboxyl­ate groups are 80.43 (17) and 62.5 (4)°. Within each SBU, the four carboxyl­ate groups come from four symmetry-equivalent tetra­fluoro­isophthalate ligands. Each tetra­fluoro­isophthalate group connects two SBUs, forming a layered structure . In the crystal, O—H⋯O hydrogen bonds involving the free and ligated methanol mol­ecules link the mol­ecules into a three-dimensional supra­molecular network.
