Whereas the use of zinc(II) salts gave rise to diamagnetic cages, iron(II) salts yielded metallosupramolecular cages that show spin-crossover behaviour in solution. The spin-transition temperature T_1/2 depends on the incorporated aldehyde component, giving a construction kit for the deliberate synthesis of spin-crossover compounds with tailored transition properties. Incorporation of 4-thiazolecarbaldehyde or N-methyl-2-imidazole-carbaldehyde yielded cages that undergo spin-crossover around room temperature whereas the cage obtained using 1H-4-imidazolecarbaldehyde shows a spin-transition at low temperatures. Three new structures were characterized by synchrotron X-ray diffraction and all structures were characterized by mass spectrometry, NMR and UV/Vis spectroscopy.Angewandte Chemie (International ed. in English)A Family of Heterobimetallic Cubes Shows Spin-Crossover Behaviour Near Room Temperature.PMC8519129SFB 813ERC Consolidator grant 683083 RAMSES683083Weisbarth RLutzen AHoriuchi SEngeser MClever GHHardy MTessarolo JBeck JHolstein JJStruch NWagner NfalseA Family of Heterobimetallic Cubes Shows Spin-Crossover Behaviour Near Room Temperature.Using 4-(4'-pyridyl)aniline as a simple organic building block in combination with three different aldehyde components together with metal(II) salts gave three different Fe₈ Pt₆ -cubes and their corresponding Zn₈ Pt₆ analogues by employing the subcomponent self-assembly approach.
