摘要

标题化合物[Zn(C8H6N4O3)]n或[Zn(L)]n [H2L是3-(6-氧-6,9-二氢嘌呤-1-基)丙酸]，结晶为非二面体孪晶。Zn(II)阳离子是四配位的，由两个L配体的两个羧酸O原子和另外两个配体的两个N原子连接。每个配体连接四个Zn(II)中心，将结构扩展为具有4连接(6(5)，4(1))拓扑结构的三维聚合物，其中包含由一维金属有机螺旋构成的二维同手性层。对该化合物的热稳定性进行了研究，表明该网络具有很高的热稳定性，在720 K的温度下保持稳定。

The purine-carboxylate-containing coordination polymer poly[[μ4-1-(2-carboxylatoethyl)-6-oxo-6,9-dihydro-1H-purin-9-ido]zinc(II)].

The title compound, [Zn(C8H6N4O3)]n or [Zn(L)]n [H2L is 3-(6-oxo-6,9-dihydro-1H-purin-1-yl)propionic acid], crystallized as a nonmerohedral twin. The Zn(II) cation is four-coordinated, ligated by two carboxylate O atoms from two L ligands and two N atoms from another two ligands. Each ligand bridges four Zn(II) centres, extending the structure into a three-dimensional polymer with a 4-connected (6(5),4(1)) topological structure containing two-dimensional homochiral layers constructed from one-dimensional metal-organic helices. Investigation of the thermal stability of the compound shows that the network has very high thermostability and is stable up to 720 K.

期刊介绍： Acta Crystallographica Section C: Structural Chemistry is continuing its transition to a journal that publishes exciting science with structural content, in particular, important results relating to the chemical sciences. Section C is the journal of choice for the rapid publication of articles that highlight interesting research facilitated by the determination, calculation or analysis of structures of any type, other than macromolecular structures. Articles that emphasize the science and the outcomes that were enabled by the study are particularly welcomed. Authors are encouraged to include mainstream science in their papers, thereby producing manuscripts that are substantial scientific well-rounded contributions that appeal to a broad community of readers and increase the profile of the authors.
