ABSTRACT: The title compound, [Cu(2)(NO(3))(2)(OH)(2)(C(12)H(8)N(4)O)(2)(H(2)O)(2)](n), consists of a neutral polymeric Cu(II) complex in which each Cu(II) atom has a distorted octa-hedral 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 from a water mol-ecule, two nitrates and two hydroxides. Two Cu(II) ions are bridged by two hydroxide anions resulting in a Cu(2)O(2) loop, located across an inversion center and 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 mol-ecule and the nitrate and hydroxide, and between the hydroxide and the nitrate. Inter-molecular ?-? inter-actions are present between pyridine rings in adjacent two-dimensional structures, with a centroid-centroid distance of 3.582?(2)?Å.
