A single crystal composed of one-dimensional coordinated polymers, [CdCl₂(1-methyl-2-pyridone)]_n, has been synthesized and characterized. This compound exhibits outstanding elastic bending due to the molecular spring nature of the CdCl₂ coordination framework and weak intermolecular interactions between the coordination chains. Owing to the helical arrangement of organic ligands surrounding the coordination structure, the compound crystallizes in a chiral space group. As a result, it displays compelling circular dichroism spectra and second harmonic generation properties.

由一维手性配位聚合物组成的弹性单晶

合成并表征了由一维配位聚合物组成的单晶[CdCl ₂ (1-甲基-2-吡啶酮)] _n 。由于CdCl ₂配位框架的分子弹性性质和配位链之间较弱的分子间相互作用，该化合物表现出出色的弹性弯曲。由于配位结构周围有机配体的螺旋排列，该化合物在手性空间群中结晶。因此，它显示出引人注目的圆二色光谱和二次谐波生成特性。
