【 摘 要 】

Treatment of scandium nitrate tetrahydrate with the tetradentate ligand H2salophen [N,N′-bis(salicylidene)-1,2-phenylenediamine] afforded the yellow dinuclear complex Sc(NO3)2(μ-salophen)Sc(salophen)(EtOH) or [Sc2(C20H14N2O2)2(NO3)2(C2H6O)] (systematic name: (ethanol-κO)bis(nitrato-κ2O,O′){μ-2,2′-[1,2-phenylenebis(nitrilomethanylylidene)]diphenolato-κ4N,N′,O,O′:κ2O,O′}{2,2′-[1,2-phenylenebis(nitrilomethanylylidene)]diphenolato-κ4O,N,N′,O′}discandium). In this compound, one salophen ligand displays a bridging coordination via the two oxygen atoms, while the other salophen ligand is attached to only one Sc center. This arrangement is stabilized by a hydrogen-bonded EtOH co-ligand, and by π–π stacking interactions between the two salophen ligands.
