Abstract:
Single-crystal-to-single-crystal (SCSC) transformations have recently been found in some molecular magnets, which involve rearrangement or dynamic movement of molecular components of the crystals. Various stimuli such as guest removal, guest exchange, ligand exchange as well as redox reactions may induce SCSC transformations. To date, only a few molecular magnets are known to exhibit SCSC transformations, which often show high-dimensional robust structures. This review mainly focuses on magnetic complexes that are robust enough to experience SCSC transformations and show magnetic changes induced by solvents in due course. This contribution is organized according to the means of solvent treatment of molecular magnets, aiming at revealing magneto-structural correlation in such SCSC transformations.

Chemical Shift: Internal References and Solvent Effects
The internal reference compound generally used in NMR spectroscopy is tetramethylsilane (TMS). TMS is preferred because it is chemically inert, soluble in NMR solvents, and easily removable. Also, the highly shielded methyl protons in TMS yield an intense...
¹H NMR: Interpreting Distorted and Overlapping Signals
As Δν decreases and the signals move closer, the doublets appear increasingly distorted. The intensities of the inner lines increase at the cost of those of the outer lines as the signals are slanted or...

Molecular Solids
Molecular crystalline solids, such as ice, sucrose (table sugar), and iodine, are solids that are composed of neutral molecules as their constituent units. These molecules are held together by weak intermolecular forces such as London dispersion forces, dipole-dipole interactions, or hydrogen bonds, which...
