摘要

Two Zn II ‐based coordination polymers (CPs) were synthesized by the hydrothermal method, using Zn(NO 3 ) 2 ·6H 2 O and furan‐2,5‐dicarboxylic acid (FDCA) in dimethylformamide (DMF) solvent, at 95?°C. Poly[tetrakis(dimethylazanium) [tetrakis(μ 2 ‐furan‐2,5‐dicarboxylato‐κ 2 O 2 : O 5 )dizinc(II)]], {(C 2 H 8 N) 4 [Zn 2 (C 6 H 2 O 5 ) 4 ]} n or {[DMA] 4 [Zn II 2 (FDC) 4 ]} n (DMA = dimethylazanium and FDC?= furan‐2,5‐dicarboxylate), (1), was obtained with a 1:1 molar ratio of Zn II and FDCA. It crystallized in the monoclinic space group C 2/ c . Coordinated by Zn II ions, FDC 2? ligands form 2 1 double‐stranded helices propagating along the b axis. The helices are interconnected and extend laterally in the a direction, forming a two‐dimensional (2D) sheet‐like network. The 2D sheets are stacked along the c direction without interconnections. DMA cations are cocrystallized in (1) and are hydrogen bonded with carboxylate O atoms of the FDC 2? ligands. The hydrogen‐bonding pattern consists of R 2 2 (4) and R 2 2 (10) motifs alternating in a chain. Poly[bis(dimethylazanium) [bis(μ 4 ‐furan‐2,5‐dicarboxylato‐κ O 2 :κ O 2′ :κ O 5 :κ O 5 )bis(μ 3 ‐furan‐2,5‐dicarboxylato‐κ O 2 :κ O 2′ :κ O 5 )dizinc(II)] dimethylformamide 3.08‐solvate], {(C 2 H 8 N) 2 [Zn 2 (C 6 H 2 O 5 ) 4 ]·3.08C 3 H 7 NO} n or {[DMA] 2 [Zn II 3 (FDC) 4 ]·3.08DMF} n , (2), was obtained with a 1:2 molar ratio of Zn II and FDCA. It crystallized in the monoclinic space group P 2 1 / c , forming a three‐dimensional network. The pores are filled with DMA cations and DMF solvent molecules.
