A novel tetranuclear cubane-like complex [Ni-4(hbzim)(4)(N-3)(4)(mal)(2)(CH3OH)(H2O)] (Hhbzim = 2-hydroxymethylbenzimidazole, mal = 4-methoxyaniline) has been synthesized and characterized structurally as well as magnetically. The structure analyses reveal that this complex consists of a Ni4O4 cubane core and the different coordinate environments of the nickel(II) ions result in a cubane structure with differing Ni-Ni distances and Ni-O-Ni angles. The magnetic properties of this complex have been interpreted by employing one-J and two-J model. The results show that ferromagnetic interaction dominates in the complex.
