X-ray powder diffraction and magnetic susceptibility measurements show that Ag(pyz)(2)(S2O8) consists of 2D square nets of Ag2+ ions resulting from the corner-sharing of axially elongated AgN4O2 octahedra and exhibits characteristic 2D antiferromagnetism. Nevertheless, mu+SR measurements indicate that Ag(pyz)(2)(S2O8) undergoes 3D magnetic ordering below 7.8(3) K.
