Synthesis, crystal structure and catalytic property of a cadmium(II) coordination polymer derived from a zwitterionic carboxylate ligand

A new Cadmium(II) zwitterionic coordination polymer, {[Cd(cbdcp)(H₂O)₄]·H₂O}_n, (1) was synthesized based on the 1-(3,5-dicarboxybenzyl)-4,4′-bipyridinium bromide (H₃cbdcpBr) organic linker. In 1, Cd(II) cations are connected by cbdcp²⁻ anions to form a one-dimensional chain structure, which are further connected to generate a hydrogen bonded-extended three-dimensional supramolecular network. Furthermore, thermal stability and catalyitic activity of 1 have also been investigated.

本文以1-(3,5-二羧基苄基)-4,4'-联吡啶溴化物（H₃cbdcpBr）为有机配体，合成了一种新型二价镉两性离子配位聚合物{[Cd(cbdcp)(H₂O)₄]·H₂O}ₙ（编号1）。在该配位聚合物（1）中，二价镉阳离子被cbdcp²⁻阴离子桥连形成一维链状结构，该链状结构进一步通过氢键作用拓展为三维超分子网络。此外，本文还对该配位聚合物（1）的热稳定性与催化活性进行了研究。
