Özet

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)degrees. The O-H center dot center dot center dot O hydrogen bonds further connect the manganese-carboxylate units. pi-pi contacts between the benzene rings [centroid-centroid distance = 3.6894 (15) angstrom] further stabilize the crystal structure.
