Tetra­kis(picolinato-κ(2) N,O)zirconium(IV) dihydrate

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 ([Image: 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-anti­prismatic coordination polyhedron of the N,O-coordination ligand atoms is formed, with a distortion towards dodeca­hedral geometry. The crystal packing is stabilized by inter­molecular π–π inter­actions 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 mol­ecules and the coordinated ligands, thereby linking the mol­ecules into a supra­molecular three-dimensional network.
