In the title compound, [Zn(C7H4FO2)2(C5H6N2)2] or [Zn(fa)2(2-pa)2] (Hfa is 2-fluorobenzoic acid and 2-pa = pyridin-2-amine), the asymmetric unit contains one ZnII cation, two fa ligands and two 2-pa ligands, wherein the ZnII displays a distorted tetrahedral geometry, being surrounded by two monodentate fa ligands with Zn—O distances of 1.962 (2) and 1.976 (3) Å, and by two 2-pa ligands with distances involving pyridyl N atoms of 2.069 (2) and 2.056 (2) Å. The F atoms of the fa ligands are equally disordered over two sites, viz. the 2- and 6-positions of fa. The mononuclear complex molecules are joined by N—H...O and N—H...F hydrogen bonds into a two-dimensional layer, which is further constructed into a three-dimensional supramolecular network by weak C—H...F interactions and effective π–π stacking [centroid-centroid separation of 3.74 (3) Å] between the interlayer aromatic rings and adjacent heterocycles.
