New tri-tert-alkyl substituted o-quinones of tetraline family

Magnetically bistable cobalt-dioxolene complexes with a tetradentate N-donor base

“…The isolated compounds demonstrate the high diversity of the magnetic properties, namely 1a, 1b, and 3 are field-induced single-ion magnets, while complex 2 shows thermally induced VT in the solid state. The obtained results create a strong conviction that the use of new sterically hindered catecholate ligands [51][52][53] possessing electron-withdrawing groups (EWGs) or electron-donating groups (EDGs) will allow us to expand the observed variability of spatial isomers and finely tune their magnetic properties.…”
