Abstract
AbstractThe dendritic triazole‐based complexes [Fe(G1‐BOC)3](triflate)2·xH2O (1; G1‐BOC = tert‐butyl {3‐[3‐(3‐tert‐butoxycarbonylaminopropyl)‐5‐([1,2,4]triazol‐4‐ylcarbamoyl)phenyl]propyl}carbamate, triflate = CF3SO3–), [Fe(G1‐BOC)3](tosylate)2·xH2O (2; tosylate = p‐CH3PhSO3–), [Fe(G1‐DPBE)3](triflate)2·xH2O {3; G1‐DPBE = 3,5‐bis(3,5‐didodecaoxybenzyloxy)‐N‐[1,2,4]triazol‐4‐ylbenzamide}, [Fe(G1‐DPBE)3](tosylate)2·xH2O (4) and [Fe(G1‐DPBE)3](BF4)2·xH2O (5) were designed and synthesized. Magnetic and thermal properties of these novel complexes were characterized by magnetic susceptibility measurements, 57Fe Mössbauer spectroscopy and thermogravimetric analysis or differential scanning calorimetry, respectively. All dendritic complexes under study show different spin‐transition behaviour with respect to the nature of different dendritic ligands and counteranions. Complexes 1 and 2 have pronounced effects of a spin‐state change during the first heating process and gradual spin‐transition properties for further temperature treatments, whereas 3 and 4 exhibited a very sharp spin‐state change in the first heating procedures. Complex 5 showed a gradual spin‐transition curve. In this paper, we report how themagnetic properties of these complexes are correlated with noncoordinated water molecules and their effects on spin states.
