Hydrothermal reactions of 4,4´-bipyridine, benzoic acid/p-methylbenzoic acid, Ni(NO3)2 · 6H2O and NH4OH yielded [Ni(bpy)1.5(H2O)2(BA)2]·H2O (1) and [Ni(bpy)(HMBA)(MBA)2]n (2) (bpy = 4,4´-bipyridine, HBA = benzoic acid, HMBA = p-methylbenzoic acid). The Ni(II) ions of compound 1 are six-coordinated and bridged by 4,4´-bipyridine ligands to form a binuclear structure while complex 2 features polymeric chains which are connected by 4,4´-bipyridine molecules. Variabletemperature magnetic susceptibility measurements from 300 to 30 K showed the presence of weak ferromagnetic interactions between the Ni(II) (S = 1) ions via the 4,4´-bipyridine bridges.
