Abstract
The α2β2 atropoisomer of meso-tetrakis(o-nicotinoylamidophenyl)–copper porphyrin leads in the presence of Cu(II) cation to coordination polymers in the crystalline phase. The networks are generated by interconnection of metalloporphyrin units through the coordination of Cu centres adopting an octahedral coordination geometry by two pyridines belonging to consecutive complexes. Depending on the solvent systems used, the 1-D coordination network based on 1α2β2 and Cu dication was shown to form a 3-D network based on a combination of three distinct supramolecular forces.
