A new supramolecular compound based on MnIII-Schiff-base and β-octamolybdate

A novel layered supramolecular compound [N(CH3)4]2[Mn(Salen)(DMF)2]2[β-Mo8O26] · 2DMF (1) (H2salen = N,N′-ethylenebis(salicylideneimine)) has been synthesized and characterized by elemental analysis, IR, TG, UV and single-crystal X-ray diffraction analysis. Compound 1 represents a new and rare example constructed by MnIII-salen Schiff-base building blocks and β-octamolybdate isopolyoxoanions. Moreover, the reaction contains the unusual N(CH3)4+ cations generated in situ from the decomposition and alkylation reaction of DMF precursors. The electrochemical of cyclic voltammetry and electrocatalytic properties of 1 have been well investigated.
