Hydrothermal reactions of rare-earth cerium with L-tartaric acid afford a new coordination polymer, namely, poly[[triaqua(μ-L-tartrato)cerium(III)] chloride], {[Ce(CHO)(HO)]Cl}, (1). The structure was determined by single-crystal X-ray diffraction analysis and further characterized by IR and UV-Vis spectroscopy, powder X-ray diffraction and thermogravimetric analysis. Single-crystal X-ray diffraction analysis revealed that the compound is a new two-dimensional (2D) double-layered structure with one-dimensional left-handed helical chains. The different intermolecular interactions were confirmed using Hirshfeld surface analysis and molecular fingerprint plots. Molecular 2D fingerprint plots quantify the different interactions and highlight that H...H (24.8%), H...O/O...H (26.3%), Cl...H/H...Cl (19.6%), O...O (13.8%) and Ce...O/O...Ce (13.6%) interactions account for 99.8% of all contacts. Additionally, the photoluminescence properties of the compound were investigated in the solid state.
水热条件下，稀土铈与 L-酒石酸反应，得到了一种新的配位聚合物，即 poly[[三 Aqua(μ-L-酒石酸)铈(III)] 氯化物]，{[Ce(CHO)(HO)]Cl}，（1）。该结构通过单晶 X 射线衍射分析确定，并通过 IR 和 UV-Vis 光谱、粉末 X 射线衍射和热重分析进一步表征。单晶 X 射线衍射分析表明，该化合物是一种具有一维左手螺旋链的新型二维（2D）双层结构。使用 Hirshfeld 表面分析和分子指纹图证实了不同的分子间相互作用。分子 2D 指纹图量化了不同的相互作用，并强调了 H...H（24.8%）、H...O/O...H（26.3%）、Cl...H/H...Cl（19.6%）、O...O（13.8%）和 Ce...O/O...Ce（13.6%）相互作用占所有接触的 99.8%。此外，还研究了该化合物在固态下的光致发光性质。
