基于4-(1-1,2,4-三唑基)苯甲酸的钙、镁配合物

Ca, Mg Ion Complexes Based on the Ligand 4-(1-1,2,4-triazolyl)Benzoic Acid

  • 摘要: 以4-(1-1,2,4-三唑基)苯甲酸(Htabc)为配体,通过水热法和溶剂挥发法合成了2种碱土金属配合物\Mg(tabc)_2(H_2O)_4\ (〖STHZ〗1)、\Ca(tabc)(H_2O)_4\(tabc) (〖STHZ〗2),并对其进行了系列性质表征. 单晶结构表明,配合物〖STHZ〗1和〖STHZ〗2分别是零维和一维配位结构,配位水分子与羧基氧形成大量氢键,分别将〖STHZ〗1和〖STHZ〗2拓展成了三维和二维超分子结构. 配合物〖STHZ〗2结构中含有1个游离的tabc-,将二维层连成三维超分子结构. 配合物〖STHZ〗1和〖STHZ〗2的固体荧光光谱表明,此2种配合物的最大发射峰对应的波长相对配体都发生了蓝移. 配合物〖STHZ〗2的热重数据显示了特殊的客体稳定化作用. 配合物〖STHZ〗1和2的CCDC号分别为1460791和1460792.

     

    Abstract: Two alkaline earth metal complexes, \Mg(tabc)_2(H_2O)_4\ (〖STHZ〗1) and \Ca(tabc)(H_2O)_4\ (tabc) (〖STHZ〗2) (Htabc=4-(1-1,2,4-triazolyl)benzoic acid) were synthesized via hydrothermal method and solvent evaporation method, respectively. The complexes were characterized. X-ray single crystal diffractions show that the complexes 〖STHZ〗1 and 〖STHZ〗2 are composed of discrete and one dimensional structure, respectively. The coordination water molecules are hydrogen bonding with the oxygen atoms of carboxylate groups, and furthermore accumulated into 3D and 2D supramolecular structure for 〖STHZ〗1 and 〖STHZ〗2, respectively. The unbounded tabc- ligands in 〖STHZ〗2 connect the 2D layers into 3D supramolecular structure via hydrogen bonding. The solid-state fluorescence spectra of 〖STHZ〗1 and 〖STHZ〗2 show that the wavelength of emission peaks are hypsochromic shift compared to that of the ligand. The TG data indicate that the free tabc- ligands in 〖STHZ〗2 can obviously stabilize the structure. CCDC numbers are 1460791 (〖STHZ〗1) and 1460792 (〖STHZ〗2).
