Synthesis,crystal structure and properties of a coordination polymer constructed by Cu~Ⅱ and cyclohexane- 1,4- dicarboxylic acid

采用1,4-环己烷二羧酸和硝酸铜,通过水热合成的方法合成了一个新的由二核铜簇构筑的金属有机一维链化合物[Cu(H2O)C8H10O4]2(1)(C8H10O4=1,4-环己烷二羧酸),并通过元素分析和X-射线单晶衍射方法对化合物1的晶体结构进行了表征.结构分析表明化合物1属于三斜晶系,P1空间群;晶胞参数为a=6.911(5),b=8.460(5),c=8.602(5),α=72.804(5)°,β=84.853(5)°,γ=85.235(5)°,V=477.7(5)3,Z=1,R1=0.0625,ωR2=0.1864.化合物1包含二核铜簇,并进一步由1,4-环己烷二羧酸共价连接构筑了一个包含环路结构的一维链.我们研究了标题化合物对亚甲基蓝的光催化效果.

Through using cyclohexane-1,4-dicarboxylic acid and Cu（NO3）2, a new one-dimensional coordination polymer containing bi-nuclear copper clusters was synthesized under hydrothermal conditions, [ Cu （H2O）C8H10O4]2（1） （C8H10O4 =cyclohexane-1,4-dicarboxylic acid）, and characterized by elemental an-alyses and single-crystal X-ray diffraction.Structural analysis shows that complex 1 crystallizes in space group P1, a=6.911（5）？,b=8.460（5） ？,c=8.602（5）？,α=72.804（5）°,β=84.853（5）°,γ=85.235（5）°,V=477.7（5） ？3 ,Z=1,R1 =0.0625,ωR2 =0.1864.Complex 1 contains bi-nuclear copper clusters, which are further linked by cyclohexane-1,4-dicarboxylic acid molecules covalently to construct a＂cycle-connecting-cycle＂ chain.We also studied the photocatalytic activity of 1 toward methylene blue （ MB） .
