چکیده
In the title compound, [Zr(C(6)H(4)NO(2))(4)]·2H(2)O, the Zr(IV) atom is located on a crystallographic fourfold rotoinversion axis ([Formula: see text]) and is coordinated by four picolinate anions with Zr-O and Zr-N distances of 2.120 (2) and 2.393 (2) Å, respectively. An approximate square-anti-prismatic coordination polyhedron of the N,O-coordination ligand atoms is formed, with a distortion towards dodeca-hedral geometry. The crystal packing is stabilized by inter-molecular π-π inter-actions between adjacent picolinate rings [centroid-centroid distances = 3.271 (1) and 3.640 (2) Å], as well as O-H⋯O hydrogen bonds between the solvent mol-ecules and the coordinated ligands, thereby linking the mol-ecules into a supra-molecular three-dimensional network.
