| titleOfInvention | High nuclear gadolinium cluster complex with large magnetocaloric effect and preparation method thereof |
| abstract | The invention relates to a high nuclear gadolinium cluster complex with a large magnetocaloric effect. The chemical formula is C110H82Gd10O56S22 which belongs to the triclinic system, and the space group is P-1. The preparation method comprises the steps of: placing gadolinium oxide, thiophene-3-carboxylic acid and water into a stainless steel reaction kettle and mixing uniformly; then, reacting for 72 hours at 150-170 DEG G; cooling to 20 DEG C to obtain block crystals; collecting the crystals and washing the crystals with water and ethanol; and vacuum drying to obtain the target product: high nuclear gadolinium cluster complex. The invention has the advantages that according to the preparation method based on large self-rotating ground state of gadolinium ions, weaker magnetic interaction among metals and larger metal ligand proportion, the high nuclear gadolinium cluster complex with the large magnetocaloric effect is prepared; the raw materials are simple and cheap to the benefit of large-scale production; and the complex has the large magnetocaloric effect, and has a huge potential application value in the aspect of magnetic refrigeration. |
