Abstract
The hydrothermal reaction of CoCO3 and 4-fluorobenzoic acid afforded the title CoII complex, [Co(C7H4FO2)2(H2O)2]n. The CoII atom is located on an inversion center and is coordinated by six O atoms from two water molecules and four μ2-carboxylate groups of 4-fluorobenzoate anions, forming a distorted CoO6 octahedron, with Co—O bond lengths in the range 2.071 (2)–2.130 (2) Å. All adjacent O—Co—O angles are in the range 84.78 (6)–95.22 (6)° and opposite angles are 180.0°. Each μ-carboxylate group of the 4-fluorobenzoate anions bridges two symmetry-related CoII atoms. Hydrogen-bonding interactions of the coordinated water molecules further connect the cobalt–carboxylate units, forming layers perpendicular to the a axis. The cobalt–oxygen layers are encased in a sandwich-like fashion by layers of π-stacked 4-fluorobenzoate anions. Within these layers the benzene rings of the 4-fluorobenzoate anions are π-stacked, with centroid–centroid distances of 3.432 (4) Å.

Summary
The CoII atom is located on an inversion center and is coordinated by six O atoms from two water molecules and four 2-carboxylate groups of 4-fluorobenzoate anions, forming a distorted CoO6 octahedron, with Co—O bond lengths in the range 2.071 (2)–2.130 (2) A. All adjacent O— Co—O angles are in the range 84.78 (6)–95.22 (6) and opposite angles are 180.0. Each -carboxylate group of the 4-fluorobenzoate anions bridges two symmetry-related CoII atoms. Hydrogen-bonding interactions of the coordinated water molecules further connect the cobalt–carboxylate units, forming layers perpendicular to the a axis. The cobalt–oxygen layers are encased in a sandwich-like fashion by layers of stacked 4-fluorobenzoate anions. Within these layers the benzene rings of the 4-fluorobenzoate anions are -stacked, with centroid–centroid distances of 3.432 (4) A
