University chemistry students are taught that the shapes and electronics of inorganic complexes are predictable. For example, d8 square-planar Pd(ii) and Pt(ii) complexes are invariably low spin, while d3–d7 tetrahedral complexes are high spin. Now, researchers in the US have thrown away the textbook by synthesising a square-planar Fe(ii) complex that is not only high spin, but has a different core (FeO2NCl) to the only other examples of this complex type, all of which feature an FeO4 core.
