A Bispidine Based CuII/ZnII Heterobimetallic Coordination Polymer

Abstract The metalloligand approach was used to obtain a novel Cu II /Zn II heterobimetallic coordination polymer (CP) 1 , based on the carefully designed bispidine ligand L4 . CP 1 , characterized by single crystal (SC‐) and powder X‐ray diffraction methods (P‐XRD), is constituted by repeating large 32‐membered macrocycles forming ribbon‐like linear arrays and it features a Cu II ‐coordination site occupied by a markedly labile MeCN. We also describe the synthesis and characterization of intermediate metalloligands (with Cu II , Fe III , Mn II , and Pd II , the latter three obtained as SCs and characterized accordingly) and provide a view of potential intermediate species along the route from metalloligands to heterometallic CPs.
