The cover picture shows the synthesis and characterization of a methoxo‐bridged dinuclear Cu II tropolonate. Three phases of this complex were structurally characterized; in all of them, the dinuclear building units aggregate via longer Cu ··· O contacts to chains. Two of the phases thus identified may be interconverted; they are metrically similar but not related by symmetry. Rather, the corresponding phase transition is reconstructive and associated with a very large hysteresis. Strong antiferromagnetic coupling has been observed for the methoxide‐bridged cations. Schnitzler et al. used diffraction and susceptibility measurements to compare the chain polymer shown in the cover picture with chemically related discrete hinokitiolato complexes on pp. 222ff.
