Complex 1 exists in the high‐spin form regardless of whether Ni is surrounded by the bidentate ligands in a planar or tetrahedral fashion. Thus, 1 is the second planar, high‐spin Ni II complex and the first for which both the planar and the tetrahedral forms could be characterized. The tetrahedral isomer predominates in solution; its NiO bonds are shorter and its NiN bonds are longer than those of the planar isomer.
