Magnetic clusters in the paramagnetic phase of a high-temperature ferromagnetic metal–organic framework

Abstract Owing to their exceptional chemical and electronic tunability, metal–organic frameworks can be designed to develop magnetic ground states — however, the typically weak exchange interactions mediated by the diamagnetic organic ligands result in ordering temperatures confined to the cryogenic limit. The itinerant magnetic ground state realized in the chromium-based framework Cr(tri) 2 (CF 3 SO 3 ) 0.33 (Htri, 1 H -1,2,3-triazole) is a remarkable exception to this trend, showing a robust f
