摘　　要：在室温条件下合成了2个多金属氧簇化合物(Hbidp)_3(PMo_(12)O_(40))·bidp (1)和(Hbid)_3(PMo_(12)O_(40))·bid (2)(bidp=苯并咪唑基苯酚,bid=苯并咪唑)。通过红外、元素分析和X射线单晶衍射分析对2个化合物进行了表征。化合物中多酸阴离子与有机组分通过氢键、静电引力及π-π堆积作用形成一维链状多金属氧簇化合物晶体。电化学性质研究表明化合物1和2均具有优良的氧化还原性质。光催化研究结果显示化合物1和化合物2对罗丹明B和亚甲基蓝具有良好的光催化降解作用。Two one-dimensional chain polyoxometallic cluster compounds connecting poly-acid anions with organic components benzimidazolyl phenol(bidp) or benzimidazole(bid) by hydrogen bond, electrostatic attraction and π-π stacking have been synthesized at room temperature, which are (Hbidp)3(PMo12O40)·bidp (1) and (Hbid)3(PMo12O40)·bid (2), and they have been unequivocally characterized by IR spectroscopy, complete elemental analysis and single crystal X-ray diffraction. The cyclic voltammogran indicted that compounds 1 and 2 have excellent redox properties. The photocatalytic performance of compounds 1 and 2 were investigated with photodegradation of methylene blue (MB) and rhodamine B (RhB) with UV irradiation. CCDC: 1458018, 1; 1469803, 2.
