A new polynuclear Fe(III) cluster based on inorganic O-donor polyoxometalate and organic N-donor ligands

A new polynuclear Fe(III) cluster based on both inorganic O-donor polyoxometalate ligand and organic N-donor ligand hexamethylenetetramine (hmta), Na9(CH3-hmta)4 (hmta)2[{Fe10−xWxH15−3xO15(hmta)2}(P2W13O51)2] · ∼70H2O (x = 0.18) (1), has been synthesized and structurally characterized, exhibiting good electrocatalytic properties to reduce the nitrites.
