Abstract The cover picture shows the influence of the bridging ligand in iron(II) 1D coordination polymers on the spin‐transition properties of those complexes. Rigid linkers like 4,4′‐bipyridine increase the cooperative interactions between the spin‐crossover centres, leading to thermal hysteresis loops. In contrast to this, flexible linkers like 1,3‐bis(4‐pyridyl)propane support the formation of zigzag chains with restraining interactions between the 1D chains that lead to stepwise spin transitions. Details are discussed in the article by B. Weber et al. on p. 2803 ff.
