Cu(pz)2(ClO4)2 belongs to a family of compounds composed of magnetic Cu2+ ions linked by pyrazine molecular units forming Cu-pz layered materials. Magnetic susceptibility, isothermal magnetization, electron spin resonance, and neutron scattering data indicate that the molecular magnet, Cu(pz)2(ClO4)2, exhibits a low dimensional antiferromagnetic character, conforming to the two dimensional Heisenberg antiferromagnetic model, with a moderate exchange strength (J = -18 K). The neutron diffraction investigation of Cu(pz)2(ClO4)2 determines the interactions which drive the systems from a two to a three dimensional antiferromagnetic phase.
