The X-ray crystal structure of [Cu(bipy)F2(H2O)]·2H2O shows it to contain five-co-ordinate copper in a square-pyramidal configuration. Each fluoride ligand is connected by short hydrogen bonds to two lattice waters with R(F ⋯ O)= 2.634–2.673 Å. Moreover the Cu–F bonds at 1.884(4) and 1.889(4)Å are the shortest such bonds known.
