Construction of Two Chiral Bilayer Coordination Polymers Based on 2-（Pyridine-3-yl）-lH-4,5- imidazoledicarboxylate Ligand

Two novel isomorphic coordination polymers [Zn（HPyImDC）H20]（1） and [Co（HPylmDC）H20]（2） were synthesized from 2-（pyridine-3-yl）-lH-4,5-imidazoledicarboxylic acid（H3PylmDC） under hydrothermal conditions. Both the compounds crystallized in P21221 chiral space group, possessing left-hand helical chains...

Summary:Two novel isomorphic coordination polymers [Zn（HPyImDC）H20]（1） and [Co（HPylmDC）H20]（2） were synthesized from 2-（pyridine-3-yl）-lH-4,5-imidazoledicarboxylic acid（H3PylmDC） under hydrothermal conditions. Both the compounds crystallized in P21221 chiral space group, possessing left-hand helical chains and right-hand helical chains. Two types of helical chains connected with each other to form an interesting 2D bilayer structure which extended to a 3D supermolecular structure via the hydrogen-bonding interactions. Topology analysis shows that H3PylmDC ligand and metal center can be regarded as 3-connected T-shaped nodes, thus leading to a （3,3）- connected network with vertex symbol of （82.10）.
