Heterodinuclear Cu-Tb single-molecule magnet

A strictly heterodinuclear Cu-Tb complex [LCu(O2COMe)Tb(thd)(2)] made with a Schiff base L, thd, and monomethylcarbonate ligands [L2- = N,N'-2,2-dimethylpropylenedi(3-methoxysalicylideneiminato); thd = tetramethylheptanedionato] behaves like a single-molecule magnet. The monomethylcarbonate ligand, which appears during the reaction pathway, bridges the Cu and Tb ions.
