[Ni(pyz)2(H2O)2](BF4)2 (pyz = N2C4H4) was synthesized by a solvent-free technique and its structure solved by synchrotron X-ray powder diffraction.1 The compound contains S = 1 Ni(II) ions and has tetragonal symmetry. Two-D [Ni(pyz)2(H2O)2]2+ square lattices propagate in the ab-plane and stack along the c-axis (Fig. 1). Water ligands occupy axial sites and form H-bonds with interlayer BF4- ions. SQUID magnetometry shows a possible transition to long-range magnetic order near 3 K. We measured the magnetization of [Ni(pyz)2(H2O)2](BF4)2 as a function of temperature to search for field-induced phase transitions and briefly report those findings here.
