摘要: 通过双苯丙咪唑作为含氮配体, 辅以对苯二甲酸配体水热合成出了一种新型的双Z链钴配合物:[Co₂(BDC)₂(H₂C₃PIm)₂(H₂O)₂]_n (1)(H₂BDC=对二苯甲酸;H₂C₃PIm=2, 2丙基双苯丙咪唑), 通过元素分析、热重以及X射线单晶洐射对其进行了表征。该晶体属正交晶系, Pca2₁空间群。每个Co(Ⅱ)原子都具有四面体配位结构, 通过BDC和H₂C₃Pim配体连接形成Z型链结构, 但由于配体BDC扭转角的不同, 导致了配合物形成了由C-H…π仔作用与分子间氢键N-H…O, O-H…O连接的一种新颖的组成相同, 结构不同的双Z型链状结构(A, B), A型Z链之间与B型Z链之间通过不同的分子间氢键相连组成三维超分子结构。室温下配合物具有较强的荧光发射光谱。

Abstract: By using the bis(2-benzimidazolyl)alkanes as the N-donor ligand and 1,4-benzenedicarboxylic acid as the second metal linker, a novel cobalt(Ⅱ) compound with a 1D double-zigzag chain structure, namely, [Co(BDC)(H₂C₃PIm)(H₂O)]_n (1) (H₂C₃PIm=2,2-(1,3-propanediyl)-bis(1H-benzimidazole), BDC=1,4-benzenedicarboxylic acid) has been synthesized under hydrothermal conditions and characterized by elemental analysis, thermal analysis, X-ray single-crystal diffraction. The crystal belongs to the orthorhombic system, space group Pca2₁ with a=1.488 6(5) nm, b=1.791 7(5) nm, c=1.894 3(5) nm, V=5.052(3) nm³, D_c=1.360 g·cm^-3, Z=8, F(000)=2 136, Goof=0.986, R₁=0.042 5, wR₂=0.068 7. In compound 1, the distorted tetrahedral Co(Ⅱ) ion is bridged by the carboxylic oxygen atoms of the BDC ligand and chelated by the nitrogen atoms of the H₂C₃PIm ligand. Owning to the different of the distorted angles from the BDC ligand, the compound units are linked into 1D double-zigzag chain structure (mode A; mode B) via the C-H…π interactions and N-H…O, O-H…O hydrogen bonding between uncoordinated carboxylate and the nitrogen atoms of H₂C₂EIm as well as the free water molecules and further extended into a 3D supramolecular structure through the intermolecular hydrogen bonds between the adjacent A and the adjacent B zigzag chains. The luminescent property of compound 1 has also been studied. CCDC: 839239.
