Grid ion : A Cu 16 grid prepared with a tetratopic bishydrazone ligand has metal ions in a [4×4] array linked by a combination of μ‐O hydrazone and μ‐NN pyridazine bridges. The six‐coordinate copper ions display Jahn–Teller distortion, leading to some orbitally orthogonal bridges. Multiple intragrid magnetic‐exchange pathways are present and are modeled simply by taking the molecular symmetry and the orthogonal connections into account.
