Abstract
A new polyoxometalate(C10H10N3)3PMo12O40(compound 1) is reported. Compound 1 has been characterized by elemental analysis, IR spectroscopy, UV-VIS-NIR reflectance spectroscopy, ESR spectroscopy and X-ray diffraction. Crystallographic parameters are as follows: triclinic, space group P1. a=11.5499(17)A，b=12.9776(16)A，c=20.3895(25)A，α=90.72(1)°，β=91.35(1)°，γ=111.43(1)°，V=2843.40(1237)A3. In the title compound, Keggin type polyanions [PMo12O40]3-and protonated 2,2′-dipyridylamine form a 3D network structure. However, part of the organic ligand 2,2′-dipyridylamine is arranged in two parallel Z type chains due to π-π stacking. Compound 1 has been incorporated in an electrode and exhibited excellent performance in the electrocatalytic reduction of ClO3-.
