Abstract
- In the title compound, [Zn(C(7)H(4)FO(2))(2)(C(5)H(6)N(2))(2)] or [Zn(fa)(2)(2-pa)(2)] (Hfa is 2-fluoro-benzoic acid and 2-pa = pyridin-2-amine), the asymmetric unit contains one Zn(II) cation, two fa ligands and two 2-pa ligands, wherein the Zn(II) displays a distorted tetra-hedral 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 mol-ecules 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 supra-molecular network by weak C-H⋯F inter-actions and effective π-π stacking [centroid-centroid separation of 3.74 (3) Å] between the inter-layer aromatic rings and adjacent heterocycles.
