摘要: 通过水热法合成了2个新的金属-有机超分子配合物[Cd(cba)2(bix)]2(1)和[Zn(cba)2(bix)]2(2)(Hcba=2-氯苯甲酸,bix=1,4-双(咪唑基-1-基)苯),并对其进行了元素分析、红外光谱、热重、荧光光谱、单晶和粉末X射线衍射测定。配合物1和2同构,均为零维结构,并且通过π-π堆积形成了三维超分子结构。此外,还用高斯09程序PBE0/LANL2DZ方法对配合物1进行了自然键轨道(NBO)分析,计算结果表明配位原子与Cd(II)离子之间存在着共价作用。 |

Abstract: Two new metal-organic supramolecular coordination compounds[Cd(cba)2(bix)]2 (1) and[Zn(cba)2(bix)]2 (2) (Hcba=2-chlorinebenzoic acid, bix=1,4-bis(imidazol-1-ylmethyl) benzene) have been hydrothermally synthesized and structurally characterized by elemental analysis, IR spectrum, TG, fluorescence spectrum, single-crystal and powder X-ray diffraction. Complexes 1 and 2 are isomorphism, and all exhibit zero-dimensional framework and display three-dimensional supramolecular network via π-π stacking interactions. In addition, natural bond orbital (NBO) of 1 were analyzed by using the PBE0/LANL2DZ method built in Gaussian09 program. The calculation results showed the obvious covalent interaction between the coordinated atoms and Cd(II) ion. |
