Synthesis, Crystal Structures, and Catalytic Properties of Dinuclear Manganese(III) Complexes Derived from N,N′-Bis(5-Methylsalicylidene)propane-1,2-Diamine

Resumo

Two centrosymmetric dinuclear manganese(III) complexes, [Mn₂L₂(N₃)₂] (I) and [Mn₂L₂(NCS)₂] (II), where L is the deprotonated form of N,N'-bis(5-methylsalicylidene)propane-1,2- diamine (H₂L), have been prepared and structurally characterized by elemental analysis, IR and UV-Vis spectra and single crystal X-ray diffraction (СIF files CCDC nos. 1553014 (I), 1553015 (II)). The Mn atoms are in octahedral coordination. Catalytic properties for epoxidation of styrene by the complexes using PhIO and NaOCl as oxidant have been studied.
