Reversible single-crystal to single-crystal transformation between triangular single-molecule toroics

We report a method for synthesizing single-molecule magnets through a single-crystal to single-crystal transformation. This process yields two single-molecule magnets with similar triangular Dy 3 cores but distinct solvents and space groups achieved via solvent exchange. Magnetic properties reveal t...

Description
Summary:We report a method for synthesizing single-molecule magnets through a single-crystal to single-crystal transformation. This process yields two single-molecule magnets with similar triangular Dy 3 cores but distinct solvents and space groups achieved via solvent exchange. Magnetic properties reveal that both Dy 3 molecules exhibit similar toroidal moments but manifest diverse multiple magnetization dynamic behaviors owing to the spin-lattice coupling influence from different solvent molecules. Single-crystal to single-crystal transformation by solvent exchange provides a new way to study magneto-structural relationships in single-molecule magnets.
