Four nonclassical
phosphomolybdates, formulated as (H2pytty)8[{Mn(H2pytty)(H2O)3}{Sr⊂P6Mo6V Mo12VIO73}]2·16H2O (1), [{Mn(H3pytty)(H2O)3}2{Sr⊂P6Mo4VMo14VIO73}]·18H2O (2), (H3pytp) (H2pytty)2[{Fe(H2O)4}{Sr⊂P6Mo3VMo15VIO73}]·5H2O (3), and (H2pytty)2[{Cd(H2O)4}{Cd(H2O)3 (H3pytty)}{Sr⊂P6Mo5VMo13VIO73}]·9H2O (4) (pytty = 3-(pyrazin-2-yl)-5-(1H-1,2,4-triazol-3-yl)-1,2,4-triazolyl; pytp = 4′-(4″-pyridyl)-2,4′:6′,4″-terpyridine)
were hydrothermally synthesized and fully characterized. The penta-
and hexa-reduced basket clusters represent the highest reduced level
of basket-based polyoxometalate so far. In addition, transition metal
complexes as bridge units were introduced to basket system for the
first time to induce rare two-dimensional inorganic–organic
hybrid layer. The results indicate that reduced degrees of the basket
clusters of compounds 1–4 can be
tuned by altering the molar ratio of organic ligand pytty and Na2MoO4. Compounds 1–4 exhibit bifunctional electrocatalytic behaviors for oxidation of
dopamine and reduction of H2O2. Electrocatalytic
mechanism, chronoamperometric experiments and electrocatalytic stability
are studied in detail. In addition, the compounds show highly efficient
catalytic ability for the degradation of typical dyes under UV irradiation.
