Abstract:

Two novel isomorphic coordination polymers [Zn(HPyImDC)H2O](1) and [Co(HPyImDC)H2O](2) were synthesized from 2-(pyridine-3-yl)-1H-4,5-imidazoledicarboxylic acid (H3PyImDC) under hydrothermal conditions. Both the compounds crystallized in P212121 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 H3PyImDC 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).
