title: Topology, chirality and interpenetration in coordination polymers.
abstract: This Viewpoint turns back the clock to 1998 when a contribution by Carlucci, Ciani, Macchi and Proserpio (Chem. Commun., 1998, 1837-1838) addressed the existence of multiple properties in coordination polymer networks and the use of topology for classifying network connectivity, thereby serving as a presage of the exponential growth in the field of coordination polymers that continues unabated to this day.
