Synthesis, structure and magnetism of a new dicubane-like ferromagnetic tetranuclear nickel cluster containing versatile azido-only bridges and a bis(bidentate) Schiff base blocker

A new tetranuclear double- open dicubane complex [Ni-4(mu(2)-N-3) (4)(mu(3)-N-3)(2)(N-3)(2)(enbzpy)(2)].2H(2)O (enbzpy = [N, N- bis( pyridin- 2-yl) benzylidene] ethane-1,2-diamine) has been characterised structurally and magnetostructurally.
