Abstract

The invention relates to the technical field of inorganic and organic hybrid materials and particularly discloses a preparation method of a tetranuclear water cluster copper-containing coordination polymer with a mixed ligand. According to the tetranuclear water cluster copper-containing coordination polymer with the mixed ligand, the molecular formula is C50H54CuF4N12O10, the polymer is a triclinic system, and a space group and the cell parameters are as shown in the specification. The tetranuclear water cluster copper-containing coordination polymer with the mixed ligand is capable of accurately measuring the positions of water molecules in crystal lattices through a single crystal X-ray diffractometer, so that various parameters of the hydrogen interaction among the water molecules can be accurately described and various physical and chemical behaviors of the water molecules in the coordination polymer can be more deeply understood. The tetranuclear water cluster copper-containing coordination polymer with the mixed ligand is easy to prepare, good in stability, few in defects of the synthetic material and high in crystallinity, and has a very good application prospect in the fields such as molecular magnets and catalysis.

Description

technical field [0001] The invention relates to the technical field of inorganic-organic hybrid materials, in particular to a tetranuclear water cluster-containing copper coordination polymer with mixed ligands and a preparation method thereof. Background technique [0002] The coordination chemistry of mixed ligands has always been one of the hot research areas of coordination chemistry. Commonly used mixed ligands include carboxylic acid ligands and nitrogen-containing ligands. Coordination polymers constructed with carboxylic acid ligands and nitrogen-containing ligands have good stability, are easy to prepare, and have a wide range of uses. They have potential applications in gas adsorption and separation, molecular magnetism, catalysis, and fluorescence. Rigid ligands are often used to support the main structure of coordination polymers, while flexible ligands can adjust their own coordination modes in the process of self-assembly to finally obtain different configurat...
