| 摘 要： | 在室温下, 由Cu(NO3)2 、1,3 -二（4 -吡啶基）丙烷(bpp)、4,4 ’ -联苯二甲酸(H2bpdc)和2,5-噻吩二甲酸(H2tdc)制备出两种新型铜( II)配位聚合物[Cu(bpp)2(bpdc)(H2O)2]n·2nH2O, 1 和[Cu(bpp)2]n·n(tdc) 7.5nH2O, 2。两个配位聚合物均为一维线型结构，铜原子均采取变形的八面体结构，在轴线方向上的两个水分子与铜原子存在较弱的配位作用。在配合物1中，两个bpdc羧酸根离子与铜原子配位，而2中的tdc羧酸离子没有与铜原子键合，只是作为反离子平衡电荷。在两个产物中， 配体bpp具有不同的构象。热重分析表明配合物1与2分别在110°C和160°C以下是稳定的。

| Abstract: | Two novel copper(II) coordination polymers [Cu(bpp)2(bpdc)(H2O)2]n · 2nH2O ( 1 ) and [Cu(bpp)2]n·n(tdc) · 7.5nH2O ( 2 ) (H2bpdc=biphenyl‐4,4′‐dicarboxylic acid, bpp=1,3‐di(4‐pyridyl)propane and H2tdc=thiophene‐2,5‐dicartboxylic acid) have been synthesized by the reactions of Cu(NO3)2 and bpp with the H2bpdc or H2tdc, respectively at room temperature . In the complexes 1 and 2 , their Cu atoms have a distorted octahedral geometry, and two water molecules coordinate weakly to the Cu atom in the long axial direction. Both complexes have one‐dimensional linear polymer structures. In complex 1 , both carboxylate groups of the bpdc can coordinate to Cu atom, while both carboxylate groups of the tdc dianion in complex 2 do not coordinate to the Cu atom, which only balance the charge. In the both complexes, the bpp ligand has different conformation: trans‐trans in complex 1 and trans‐gauche in complex 2 . The thermal gravimetric analyses indicate that both complexes are stable under 110 and 160 °C, respectively. |
