Abstract

The invention relates to a three-dimensional 4f-5d coordination polymer and a preparation method and application thereof. The three-dimensional 4f-5d coordination polymer Ln(H2O)4(pyrazine)0.5W(CN)8 is prepared by using a mixing method which takes a neutral two-dimensional layered coordination polymer as a building block and taking pyrazine as a columnar ligand and puts the neutral two-dimensional layered coordination polymer and the pyrazine into acetonitrile, wherein Ln is any one of La, Ce, Pr, Nd, Sm, Eu, Gd and Tb. The coordination polymer has a ferromagnetic coupling mutual effect and has a significant application prospect in the field of magnetics.

Description

technical field

[0001] The invention belongs to the technical field of synthesis of molecular-based magnetic materials, in particular to the synthesis and application of a coordination polymer material. Background technique

[0002] Cyanometallic complexes are at the forefront of inorganic chemistry due to their novel topologies and interesting properties. In recent years, octacyanometallic salts with high coordination numbers [M(CN) 8 ] 3- (M=Mo, W) or [Nb(CN) 8 ] 4- began to attract widespread attention, such as P.; Korzeniak, T.; Podgajny, R.; Sieklucka, B. Coord. Chem. Rev. 2006, 250, 2234-2260. Paramagnetic [M(CN) 8 ] 3- (M=Mo, W) or [Nb(CN) 8 ] 4- Coordination polymers assembled with transition metals exhibit different dimensional structures and unique magnetic properties, such as high Curie temperature, light-induced magnetism, and single-molecule magnetism.
