位于三维超分子网格的螺旋孔道中的螺旋水链

摘要

A novel compound [Co(H2 abt)2 (H2 O)4 ]·H2 O (1) (H3 abt = Azobenzene‐3 ,5 ,4′‐tricarboxylic acid) was synthesized under hydrothermal reaction and characterized by elemental analysis ,infrared spectrum (IR) ,thermogravimetric analysis (TGA) and single‐crystal X‐ray diffraction .Structure analysis shows that complex 1 has the 3D supramolecular network with helical channels ,in which both handedness helical water chains were trapped by the coordina‐tion interactions as well as hydrogen bonds .%以偶氮苯‐3，5，4′‐三羧酸（H3abt）为配体，在水热条件下合成了一个新颖的配合物[Co（H2abt）2（H2O）4]·H2 O（1），并通过元素分析、红外光谱、热重分析和X射线单晶衍射对其结构进行了表征。结构分析显示，配合物1具有含螺旋孔道的三维超分子网格结构，两种手性的螺旋水链通过配位作用和氢键固定于螺旋孔道中。
