The cover picture shows how oximate‐bridged heterometallic trinuclear Ni II M III Ni II complexes can easily be constructed from the assembly of the “in situ” generated fac ‐O 3 [Ni(HL) 3 ] – (H 2 L = pyrimidine‐2‐carboxamide‐oxime) metalloligand (blue screw) with either M 2+ ions (M 2+ = Mn and Fe), which are oxidized during the course of the reaction, or Tb 3+ ions (red nut). The nickel(II) ions in these centrosymmmetric trinuclear complexes exhibit opposite propeller‐like chirality (the blue screws turn on the red nut in opposite directions). The red and green arrows are the spins of the M 3+ and Ni 2+ ions, and they are antiparalell, which indicates that the interaction is antiferromagnetic in nature. Details are discussed in the article by E. Colacio et al. on p. 5225 ff.
