Abstract

The invention relates to a mixed valence copper (I / II) complex magnetic material containing a 1, 2, 4-triazole and 5-isophthalic acid mixing ligand as well as a preparation method and an application thereof. The chemical formula of the complex magnetic material is [CuI0.5CuII1.5(H2O) (trz)2(H0.5nip)], wherein trz is a 1, 2, 4-triazole-valence anion, and H0.5nip is a 5-isophthalic acid-1.5 valence anion. The complex magnetic material is prepared by adopting a hydrothermal method and has higher yield and good repeatability. The complex magnetic material is a mixed valence copper (I / II) complex simultaneously containing the 1, 2, 4-triazole and 5-isophthalic acid ligand, has the remarkable spontaneous magnetization behavior at a low temperature, can be taken as a molecule-based magnetic material and has huge application value in the field of materials science.
