Pre-organization of clefts for Ag-π interactions in Zn(II) bisdipyrrin helicates for the construction of heterometallic networks

Abstract

Coordination of 2,2′-bisdipyrrin based ligands to Zn(ii) cations leads to the formation of binuclear helicates with pre-organized pyrrolic strands as well as peripheral aromatic moieties for Ag-π interactions, thus affording crystalline heterometallic networks upon further interactions with Ag(i) salts without the assistance of additional heteroatom-based coordinating units.
