An Exceptional 54-Fold Interpenetrated Coordination Polymer with 103-srs Network Topology

Entanglement is one of the most important features of coordination polymer frameworks and has attracted considerable attention due to its aesthetic and topological interest. Among entangled systems, interpenetrating frameworks represent an intriguing subset; however, there are few examples of materials containing very high levels of interpenetration. In this work a coordination polymer with 103-srs topology, constructed from a star-like tridentate ligand, tri(4-imidazolylphenyl)amine, and AgI ions, has been hydrothermally synthesized. It contains a record 54 interpenetrating networks.
