Abstract

The reactions of calcium hydroxide with pivalic, 1-naphthoic, and 2-furancarboxylic acids afford the corresponding polymeric calcium carboxylates. Depending on the crystallization conditions, calcium pivalate is isolated as two different coordination polymers: [Ca₃(Piv)₆(DMF)₂]_n·0.635nC₆H₆·0.365nDMF (I) and [Ca(Рiv)(H₂O)_2.333(DMF)_0.666]_n·nРiv·0.333H₂O (II). The synthesized calcium 1-naphthoate contains coordinated water molecules [Сa(Naph)₂(H₂O)₂]_n (III), and calcium furoate [Ca(Fur)₂]_n (IV) contains no ancillary ligands. The structures of compounds I–IV are determined by X-ray diffraction (XRD) (CIF files CCDC nos. 2342790–2342793, respectively). The structures of compounds I–III are characterized by the 1D polymeric structure, and compound IV is the 3D polymer.

聚合羧酸钙的合成及x射线结构

氢氧化钙与戊酸、1-萘酸和2-呋喃羧酸反应生成相应的聚合羧酸钙。根据结晶条件的不同，分离得到两种不同的配位聚合物：[Ca3(Piv)6(DMF)2]n·0.635nC6H6·0.365nDMF (I)和[Ca（Рiv）（H2O）2.333(DMF)0.666]n·nРiv·0.333H2O （II）。合成的1-萘酸钙含有配位水分子[Сa(Naph)2(H2O)2]n (III)，而糠酸钙[Ca(Fur)2]n （IV）不含辅助配体。化合物I-IV的结构由x射线衍射（XRD）测定（CIF文件CCDC号分别为2342790-2342793）。化合物I-III的结构为一维聚合物结构，化合物IV为三维聚合物。
