Samarium metal complex constructed by furantetracarboxylic acid and preparation method thereof

Abstract

The invention relates to a samarium metal complex constructed by furantetracarboxylic acid and a preparation method thereof. The chemical composition of the complex contains a furantetracarboxylic acid (H4fa) ligand. The synthesis scheme comprises the following steps of: respectively dissolving potassium salt of furantetracarboxylic acid and SmCl3.6H2O in distilled water according to a stoichiometric ratio, mixing, and adding 1d HCl; and putting the obtained solution into a polytetrafluoroethylene lining, then putting the polytetrafluoroethylene lining into a reaction kettle, putting the reaction kettle into a drying oven, and carrying out heating reaction for 3 days to obtain a target product. The mass ratio of the potassium salt of furantetracarboxylic acid to SmCl3.6H2O is 1: 0.91.

[0001] The invention relates to a samarium metal complex constructed by furan tetraacid and a preparation method thereof, belonging to the field of metal complex science and technology.

[0002] technical background

[0003] Metal-organic complex materials constructed by metal ions and organic ligands have broad application prospects in the fields of gas storage, optoelectronic materials, magnetic materials, and catalysis due to their diverse structures and unique properties. Compared with the d-group transition metal organic complexes and the main group metal organic complexes, the properties of the rare earth metal organic complexes are significantly different. This is because the rare earth metal ions have the characteristics of large radius and high coordination number, which are more conducive to Coordination and activation of compounds. The 4f orbital does not participate in bond formation due to the strong shielding effect, and the 18-electron rule of ...
