  摘要：

  摘要 基于1,4-双(2-甲基咪唑-1-基甲基)-2,3,5,6-四甲基苯(bmimx)的两个互穿网络，即{[Zn2(bmimx)2(cba)2]·2.5 H2O}n (1) 和 {[Zn(bmimx)(suc)]·2H2O}n (2)（H2cba = 4,4'-羰基二苯甲酸，H2suc = 琥珀酸）已在水热条件下通过改变二羧酸盐制备配体。单晶 X 射线衍射表明，配合物 1 显示出具有 3 倍互穿的 4 连接 dmp 网络，其中包含 1D (Zn − cba)n 右手和左手螺旋链；复合体 2 显示了具有 4 重互穿的 dia 拓扑。结果表明，二羧酸共配体的间隔基对互穿性状和最终骨架有重要影响。此外，在室温和固态下研究了两种配合物的光致发光特性。

  In order to tune the architectures of Cd(II)-bmimx coordination polymers (bmimx = 1,4-bis(2-methylimidazol-1-ylmethyl)-2,3,5,6-tetramethylbenzene), four dicarboxylate ligands, succinic acid (H(2)suc), 1,4-benzenedicarboxylic acid (H(2)bdc), 4,4'-sulfonyldibenzoic acid (H(2)sdba) and 4,4'-carbonyldibenzoic acid (H(2)cba), have been employed as co-ligands, and four new coordination polymers with different entangled modes, namely [Cd(bmimx)(suc)]center dot 2H(2)O)(n) (1), [Cd(bmimx)(bdc)(H2O)](n) (2), [Cd(bmimx)(sdba)](n) (3) and [Cd(bmimx)(cba)center dot 8H(2)O)(n) (4), have been synthesized and characterized. Complexes 1 and 2 show the dia topology with the 4- and 5-fold interpenetrating modes, respectively. Complexes 3 and 4 exhibit different 2D + 2D -> 3D polycatenated networks via Hopf links, respectively. A comparison of these structures reveals that the backbones of the dicarboxylate ligands play important roles in controlling the entangled modes of the coordination polymers. Furthermore, the thermal stabilities and the photoluminescence of 1-4 have also been investigated. (C) 2015 Elsevier Ltd. All rights reserved.

  Two new complexes [Cd(bmimx)(0.5)(tbip)(H2O)] center dot H2O}(n) (1) and [Zn(bmimx)(tbip)](n), (2) (bmimx = 1,4-bis(2-methylimidazol-1-ylmethyl)-2,3,5,6-tetramethylbenzene, H(2)tbip = 5-tert-butyl isophthalic acid) based on mixed ligands have been hydrothermally synthesized by varying the metal ions. Structural analysis reveals that complex 1 displays a 2D layer structure with a 4(4)-sql topology; complex 2 exhibits a 3D 4-fold interpenetrated framework with sra topology. The structural differences between 1 and 2 indicate that metal ions have significant effects on the formation of the final architectures. In addition, the thermal stabilities and photoluminescent properties of the two complexes were also investigated. (C) 2013 Elsevier B.V. All rights reserved.
