Polyoxometalates modified with complex cations have attracted increasing attention because of the fascinating properties and the controllable structures.By adjusting the synthesis conditions,four new terpyridine complexes based hybrid POMs,[(TPY-H)CuCl]4[W10O32]-2DMF-2H2O(1),[(TPY-H)Cu(DMSO)(H2O)]2[W10O32]-2H2O(2),[(TPY-H)2Cu]2[W10O32]-6DMSO-8H2O(3)and[(TPY-Br)CuCl(DMSO)(H2O)]2[(TPY-Br)CuCl]2[W10O32]-2DMSO-4H2O(4),were prepared by using'one-pot'method.Sing-crystal X-ray diffraction anal-yses,infrared radiation,etc.,revealed the structural composition of compounds 1-4,which indicates that synthesis conditions have a directional regulatory effect on the compounds synthesis.Thioether oxidation catalytic reactions show 1-4 have good catalytic activi-ties,and powder X-ray diffraction and thermogravimetry analysis show 1-4 have superduper catalytic stability.Moreover,4 has bet-ter catalytic activity because of the different structure of terpyridine complexes.Therefore,a possible mechanism of dual-site catalysis by both cations and anions is proposed.
