摘　　要：本文在水热条件下合成了一例同多钼酸阴离子[δ-Mo_(8)O_(26)]^(4-)基配合物[Co(bipbc)(δ-Mo_(8)O_(26))_(0.5)(H_(2)O)_(3)](bipbc=4,4-双[(4-羧基吡啶)甲基]联苯),其为一维链状结构,包含环型双核钴配合物[Co_(2)(bipbc)_(2)]^(4+)和[δ-Mo_(8)O_(26)]4-簇。该配合物结晶于单斜晶系,P 2_(1)/n空间群,a=1.1479(8)nm,b=1.4409(11)nm,c=2.0829(16)nm,β=93.469(2)°,V=3.4388(4)nm^(3),Z=4,M_(r)=1129.18,F(000)=2204,μ=1.979 mm-1,D_(c)=2.181 mg·m^(-3),S=1.019,R_(1)=0.0562,wR_(2)=0.1377。光催化性质研究表明,在可见光、近红外光和全光谱的光照条件下,标题配合物对龙胆紫(GV)和亚甲基蓝(MB)的降解,表现出一定的光催化活性。In this paper,a new isopolymolybdate anion[δ-Mo_(8)O_(26)]^(4-)-based complex[Co(bipbc)(δ-Mo_(8)O_(26))_(0.5)(H_(2)O)_(3)](bipbc=4,4′-bis[(^(4-)carboxypyridino)methyl]biphenyl)was synthesized under hydrothermal conditions.The title complex shows a 1D chain,which consists of the cyclic dinuclear cobalt complexes[Co_(2)(bipbc)_(2)]^(4+)and[δ-Mo_(8)O_(26)]^(4-)clusters,and crystallizes in the monoclinic system,space group P 2_(1)/n with a=1.1479(8)nm,b=1.4409(11)nm,c=2.0829(16)nm,β=93.469(2)°,V=3.4388(4)nm^(3),Z=4,M_(r)=1129.18,F(000)=2204,μ=1.979 mm-1,D_(c)=2.181 mg·m^(-3),S=1.019,R_(1)=0.0562,wR_(2)=0.1377.The investigations on photocatalytic properties show that the title complex has photocatalytic activities toward the degradation of gentian violet(GV)and methylene blue(MB)under visible,even near-infrared and full spectrum light irradiation.
