Poly[[Diaqua­Manganese(Ii)]-Bis­(Μ-4-Fluoro­Benzoato-Κ2 O:O′)]

Abstract

In the crystal structure of the title complex, [Mn(C7H4FO2)2(H2O)2]n, the MnII 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 MnII 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—H⋯O hydrogen bonds further connect the manganese-carboxyl­ate units. π–π contacts between the benzene rings [centroid-centroid distance = 3.6894 (15) Å] further stabilize the crystal structure.
