摘要：

A pair of enantiopure mononuclear dysprosium/salen-type complexes (Et3NH)[Dy((R,R)/(S,S)-3-NO(2)salcy)(2)] (1R/1S), where 3-NO(2)salcyH(2) represents N,N'-(1,2-cyclohexanediylethylene)bis(3-nitrosalicylideneiminato), are reported. The enantiomer contains two crystallographically independent dysprosium(III) ions, each chelated by two enantiopure 3-NO(2)salcy(2-) ligands forming a [DyN4O4] core. Detailed magnetic studies on compound 1R reveal a field-induced dual magnetic relaxation behavior, originating from single ion anisotropy and intermolecular interactions, respectively.
