以1，4-环己二醇（顺/反混合物）为原料，经三步反应合成了非对映体纯的反式-1，4-环己烷二磺酸H2 CDS。结晶锌盐每个分子式单元含有两个分子DMF。在[Zn（CDS）（dmf）2]的固态结构中观察到无限的聚合物带。这些平带是通过连接两条Zn（dmf）-CDS聚合物链而形成的，其中一条链上具有四面体配位的Zn 2+离子，而第二条链上具有八面体配位的Zn 2+中心。该聚合物的热分析揭示了其高达400°C的稳定性，高于该温度，其在形成结晶ZnO的情况下完全分解。
Diastereomerically pure trans-1,4-cyclohexanedisulfonic acid H2CDS was prepared in three steps from 1,4-cyclohexanediol (cis/trans-mixture) as a new linker molecule for metal–organic coordination polymers. The crystalline zinc salt contained two molecules DMF per formular unit. Infinite polymeric belts were observed in the solid state structure of [Zn(CDS)(dmf)2]. These flat belts were formed by connecting two chains of Zn(dmf)-CDS-polymers bearing tetrahedrally coordinated Zn2+ions in one chain and octahedrally coordinated Zn2+centers in the second. Thermal analysis of this polymer revealed its stability up to 400°C, above which it decomposed cleanly under formation of crystalline ZnO.
