2D-Coordination Polymer Containing Interconnected 82-Membered Organotin Macrocycles

A two-dimensional coordination polymer [(n-Bu3Sn)4(μ-L)2(4,4′-bipy)]n (1) was prepared in a reaction between (n-Bu3Sn)2O, (E)-5-(pyridin-4-yl-methyleneamino)­isophthalic acid (LH2), and 4,4′-bipyridine (4,4′-bipy). The structure of 1 is built by the interlinking of 82-membered macrocyles. The generation of the 2D coordination polymer is facilitated by the multisite coordination capability of the dianionic ligand (L2–) as well as involvement of 4,4′-bipyridine as an ancillary ligand.本研究通过三丁基氧化锡[(n-Bu3Sn)2O]、(E)-5-(吡啶-4-基亚甲氨基)间苯二甲酸（LH2）与4,4′-联吡啶（4,4′-bipy）发生反应，成功制备得到二维配位聚合物[(n-Bu3Sn)4(μ-L)2(4,4′-bipy)]n（记为化合物1）。化合物1的结构由82元大环相互交联构筑而成。二价阴离子配体(L²⁻)的多位点配位特性，以及4,4′-联吡啶作为辅助配体的参与，共同促成了该二维配位聚合物的生成。
