| 中文摘要: |
| 采用水热法,用4,4′-二(1-咪唑基)苯硫醚(BIDPT)和均苯三甲酸(H3btc)与Co(NO3)2·6H2O反应,合成了一个基于三核钴单元的一维链配合物{[Co3(BIDPT)4(btc)2(H2O)2]·H2O}n(1)。X单晶射线分析表明,配合物是为单斜晶系,Pc空间群,分子质量Mr=4 264.21(8),a=1.019 3(3) nm,b=1.783 0(5) nm,c=2.364 6(6) nm,β=102.45°,V=4.196 2(2) nm3,Z=2,Dc= 2.300 g/cm3,F(000)=2 814,S=1.042,R1=0.056 0,wR2=0.184 2 (I >2σ(I))。配合物1中,质子化的均苯三甲酸链接Co(1)和Co(3)形成了两条一维链。而这两条一维链与Co(2)和BIDPT构成的“8”字构型相连,形成了另外一条一维链。配合物中存在C－H…π堆积作用使一维链连接形成二维超分子结构。另外对配合物红外、元素分析、热稳定性以进行了测试。研究了配合物1对藏红T的催化降解性能,在氙灯照射和H2O2存在的条件下,配合物1对藏红T具有较好的光催化降解作用。 |
