The cover picture shows an imaginary animal formed by the union of two scorpions without a sting to form Siamese twins. In a surrealistic way, the shadow of this animal represents the scaffold of the set of ligands used in this work. The ligand represented contains a biphenyl moiety with two bis(3,5‐dimethylpyrazolyl)methane groups at each end. We propose for these ligands the name “di‐scorpions”. As in the animal with two pairs of claws, the pairs of pyrazolyl rings are oriented towards opposite ends of the ligand. This orientation persists in the structures of the resulting complexes after the ligands react with various metallic units. Dinuclear species and zigzag or helical polymers have been obtained. Details are discussed in the article by B. R. Manzano et al. on p. 5943 ff . For more on the story behind the cover research, see the Cover Profile .
