Abstract

In the title compound, [Zn(C₆H₃FNO₂)₂(H₂O)₄]·2H₂O, the Zn^II atom is octahedrally coordinated in a ZnO₄N₂ environment by two 3-fluoropyridine-4-carboxylate (3-fpy4-cbx) ligands and four water molecules. The [Zn(3-fpy4-cbx)₂(H₂O)₄] molecules form a three-dimensional network through strong O-HO and weak O-HF hydrogen bonds between 3-fpy4-cbx and water molecules. The crystal used for data collection was a twin, with the twin law corresponding to a 180° rotation about the real-space [001] axis. The major twin fraction refined to 0.795 (1).
