A number of salophen ligands and their Zn, Ni, and Pd complexes were synthesized by an efficient one-pot mechanosynthesis protocol. The reaction products were characterized by means of complementary solid-state techniques, i.e., powder X-ray diffraction, single-crystal X-ray diffraction, and solid-state NMR spectroscopy. Four new crystal structures of metal salophen complexes as DMSO solvates are here reported. The described simple and relatively fast (about 1 h for all derivatives) procedure is a good alternative to classical methods performed in organic solvents.
A suitable arrangement of the ligand charge can complement a low symmetry system and induce an excellent unexpected SMM behavior.
A series of Zn–Ln double-decker tetranuclear complexes display slow magnetic relaxation, in which Yb congeners show both slow magnetic relaxation and NIR properties. The magneto-structural and magneto-optical correlations are studied.
