title: Tetra-aqua-bis(3-fluoro-pyridine-4-carboxyl-ato-κN)zinc(II) dihydrate.
abstract: In the title compound, [Zn(C(6)H(3)FNO(2))(2)(H(2)O)(4)]·2H(2)O, the Zn(II) atom is octa-hedrally coordinated in a ZnO(4)N(2) environment by two 3-fluoro-pyridine-4-carboxyl-ate (3-fpy4-cbx) ligands and four water mol-ecules. The [Zn(3-fpy4-cbx)(2)(H(2)O)(4)] mol-ecules form a three-dimensional network through strong O-H⋯O and weak O-H⋯F hydrogen bonds between 3-fpy4-cbx and water mol-ecules. 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).
