A Ni 4 O 2 core based on a “chair” topology forms the central unit of the tetranuclear nickel( II ) complex 1 , which possesses μ 3 ‐OH − and butane‐2,3‐dione‐monooximate bridges and displays fascinating magnetic properties. The major Ni–Ni interactions in 1 are antiferromagnetic in nature, and the large Ni core ‐O‐Ni terminal angle in the core is responsible for driving all the Ni core spins parallel.
