Abstract

A number of salophen ligands and their Zn, Ni, and Pd complexes were synthesized by anefficient one-pot mechanosynthesis protocol. The reaction products were characterized by means ofcomplementary 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 DMSOsolvates 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.
