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.</pubmed_abstract><journal>Acta crystallographica.
