Abstracts

Structural analysis of [Ni(en)(H_2O)_4][SO_4]·2H_2O was performed and it suggests that the crystal field should play a dominant role in the magnetic properties of the system. This conjecture coincides well with the specific heat and susceptibility behaviour. The analysis confirmed that the compound can be treated as a spin 1 single molecule magnet with nonmagnetic ground state introduced by easy-plane single-ion anisotropy D/k_B≈11 K and neglecting in-plane anisotropy E/D <0.1.
