This study reports the temperature dependences of magnetic properties of NbO-type Cu-2 metal organic frameworks (MOF). Using the isotropic Heisenberg Hamiltonian and the coupling constant, which is taken in the literature, it is found that the Neel temperature of these complexes is too low. It is suggested that the Neel temperature may be increased by some geometrical distortion.
