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.
