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.

一种轴向配位空间宽阔的一维二价铜(Cu(II))配位聚合物{[Cu(bpetha)(2,2′-bpy)(MeOH)]·2PF6}n（bpetha即1,2-双(4-吡啶基)乙烷；2,2′-bpy即2,2′-联吡啶）经理性合成并完成晶体学表征；该聚合物中[Cu(2,2′-bpy)]结构单元由bpetha配体桥联，形成一维锯齿状链结构，该链结构对乙醇(EtOH)、甲醇(MeOH)及水蒸气(H2O)展现出平滑的吸附性能。
