Abstract

A novel ladder-chain cobalt(II) coordination polymer, {[Co(CHClO)(CHN)(HO)]·2CHOH} , was synthesized and characterized. The structure contains two Co centres with different octa-hedral environments, [Co(1)NO] and [Co(2)NO]. The -donating 3-chloro-benzoate anions (3-Clbenz) act as the terminal ligands, while the -donating 4,4'-bipy mol-ecules play the role of linkers. The Co(1) ions are linked by 4,4'-bipy mol-ecules into linear chains. Two such chains are joined by [Co(2)(3-Clbenz)(HO)] units two 4,4'-bipy bridging ligands, thus forming the ladder-chain structure. The crystal packing of the title compound is stabilized by supra-molecular inter-actions, such as hydrogen bonding, π-π and halogen⋯π contacts, giving a three-dimensional framework. The spectroscopic and thermal properties of the title compound have also been investigated.

摘要

合成并表征了一种新型的梯链钴(II)配位聚合物{[Co(CHClO)(CHN)(HO)]·2CHOH} 。该结构包含两个具有不同八面体环境的钴中心,即[Co(1)NO]和[Co(2)NO]。具有给电子能力的3-氯苯甲酸根阴离子(3-Clbenz)作为末端配体,而具有给电子能力的4,4'-联吡啶分子则充当连接体。Co(1)离子通过4,4'-联吡啶分子连接成线性链。两条这样的链通过[Co(2)(3-Clbenz)(HO)]单元和两个4,4'-联吡啶桥连配体相连,从而形成梯链结构。标题化合物的晶体堆积通过诸如氢键、π-π和卤素⋯π接触等超分子相互作用得以稳定,形成三维框架。还研究了标题化合物的光谱和热性质。
