Design of 2-D hydrogen bonded molecular networks using pyromellitate dianion and cyclic bisamidinium dication as complementary tectons

Using both H-bonding and ionic interactions, a dicationic tecton composed o f two cyclic amidinium units and bearing four H-bond donor sites was self-a ssembled in the crystalline phase into a 2-D molecular networks in the pres ence of pyromellitate dianion.
