Influencing the properties of dysprosium single-molecule magnets with phosphorus donor ligands. NATURE COMMUNICATIONS 6 (1). ScholarBank@NUS Repository. https://doi.org/10.1038/ncomms8492 | Abstract: | Single-molecule magnets are a type of coordination compound that can retain magnetic information at low temperatures. Single-molecule magnets based on lanthanides have accounted for many important advances, including systems with very large energy barriers to reversal of the magnetization, and a di-terbium complex that displays magnetic hysteresis up to 14K and shows strong coercivity. Ligand design is crucial for the development of new single-molecule magnets: organometallic chemistry presents possibilities for using unconventional ligands, particularly those with soft donor groups. Here we report dysprosium single-molecule magnets with neutral and anionic phosphorus donor ligands, and show that their properties change dramatically when varying the ligand from phosphine to phosphide to phosphinidene. A phosphide-ligated, trimetallic dysprosium single-molecule magnet relaxes via the second-excited Kramers' doublet, and, when doped into a diamagnetic matrix at the single-ion level, produces a large energy barrier of 256cm-1 and magnetic hysteresis up to 4.4K. | Source Title: | NATURE COMMUNICATIONS | URI: | https://scholarbank.nus.edu.sg/handle/10635/228721 | ISSN: | 2041-1723 | DOI: | 10.1038/ncomms8492 |
