MnIII–Salen composite materials based on Keggin heteropolyanions exhibiting photocatalytic and electrocatalytic activities

Two new inorganic–organic hybrid supramolecular compounds based on Keggin-type polyoxoanions, namely [Mn(salen)(CH3OH)2]3[PMo12O40] (1) and [Mn(salen)(CH3OH)2]3[PW12O40] (2) (H2salen = N,N′-ethylenebis(salicylideneimine)) have been synthesized and characterized by single-crystal X-ray diffraction analysis, elemental analysis, IR spectroscopy, and TG analysis. Two compounds reported herein represent the first examples of integrating metal–Schiff-base segments with Keggin polyanions characterized via single-crystal X-ray diffraction. Such hybrid materials display photocatalytic and electrocatalytic bifunctional catalytic activities.
