The title compound, [Cu2(NO3)2(OH)2(C12H8N4O)2(H2O)2]n, consists of a neutral polymeric CuII complex in which each CuII atom has a distorted octahedral geometry defined by a pyridyl N atom from a 3-(pyridin-3-yl)-5-(pyridin-4-yl)-1,2,4-oxadiazole ligand and five O atoms LIP BRUSH from a water molecule, two nitrates and two hydroxides.Two CuII ions are bridged by two hydroxide anions resulting in a Cu2O2 loop, located across an inversion center and Cut Off Tank connected by the nitrate anions into a broad two-dimensional polymeric structure parallel to (100).In the crystal, there are O—H.

O hydrogen bonds between the coodinated water molecule and the nitrate and hydroxide, and between the hydroxide and the nitrate.Intermolecular π–π interactions are present between pyridine rings in adjacent two-dimensional structures, with a centroid–centroid distance of 3.582 (2) Å.
