Rational Construction of Wide Coordination Space and Control of Adsorption Properties in One-Dimensional Cu(II) Coordination Polymer

A one-dimensional Cu(II) coordination polymer {[Cu(bpetha)(2,2′-bpy)(MeOH)]·2PF6}n (bpetha =1,2-bis(4-pyridyl)ethane; 2,2′-bpy =2,2′-bipyridine) with wide coordination space at the axial site was rationally synthesized and crystallographically characterized, in which [Cu(2,2′-bpy)] units are bridged by bpetha ligands, forming a one-dimensional zigzag chain that shows smooth adsorption for EtOH, MeOH, and H2O vapors.
