Dinuclear Species versus Zigzag or Helical Polymers in Palladium, Zinc, and Copper Complexes with Ditopic Bis(pyrazolyl)methane Ligands

Invited for the cover of this issue is the group of Félix Jalón and Blanca Manzano at the University of Castilla‐La Mancha‐IRICA. With the cover image of a strange animal formed by the union of two scorpions, the authors simulate the structure and the coordination ability of a ligand that appears as the shadow of this animal. The claws of the animal are pyrazolyl rings, the binding sites of this ligand to metallic centers. The image also contains the metallic compounds used to generate dinuclear complexes or zigzag or helical polymers. Our group became fascinated by the structural possibilities and the reactivity of ligands known as scorpions and scorpionates...
