Abstract: In the crystal structure of the title complex, [Mn(C₇H₄FO₂)₂(H₂O)₂]_n, the Mn^II atom is located on an inversion centre. It is coordinated by two water molecules in the apical directions and four 4-fluorobenzoate (PFB) anions, bridging the symmetry related Mn atoms in the basal plane to form an infinite two-dimensional polymeric structure parallel to (100). The four O atoms of the PFB anions around the Mn^II atom form a slightly distorted square-planar arrangement, while the slightly distorted octahedral coordination is completed by the two O atoms of the water molecules. The dihedral angle between the carboxylate group and the adjacent benzene ring is 27.29 (16)°. The O-HO hydrogen bonds further connect the manganese-carboxylate units. - contacts between the benzene rings [centroid-centroid distance = 3.6894 (15) Å] further stabilize the crystal structure.
