摘要

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.
