Coordination balance cationic salt, and magnet formed by metal dithiolene complex and preparation methods thereof

Abstract

The invention belongs to the field of functional materials, and particularly relates to a coordination balance cationic salt, and a magnet formed by a metal dithiolene complex and preparation methods thereof. The coordination balance cationic salt reacts with coordination anions to obtain the metal dithiolene complex; on one hand, the 4-iodobenzyl and 4-phenylpyridin in the coordination balance cation are respectively of a plane structure, the plane structures respectively have a symmetric axis, and are crossed at the connected carbon atom of 4-iodobenzyl and 4-phenylpyridin, and the whole inverted Y-shaped structure is formed; on the other hand, the coordination anion is of a plane structure, and the self-rotation density of the unpaired electrons is distributed on the whole anion skeleton. By adopting the structure, the magnet formed by the coordination balance cations and coordination anions is of an equal-spacing arrangement structure, the cations and anions are stacked into columns by lines, and the electron transmission and self-rotation coupling of the metal dithiolene complex are favorably performed. The magnet formed by the metal dithiolene complex has the advantages that the technology is simple, the control is easy, the reaction speed is quick, and the product purity is high.

Description

technical field [0001] The invention belongs to the field of functional materials, and in particular relates to a coordination balance cation salt, a magnet formed from a metal disulfide complex and a preparation method thereof. Background technique [0002] In recent years, complexes have become the focus of attention due to the diversity of their structures and their potential applications as functional materials in catalysis, electrical conductivity, magnetism, luminescence, and nonlinear optics. Metal disulfide complexes as typical complexes, such as figure 1 As shown, structurally, it has two characteristics: planar molecular configuration and delocalized negative charge distribution. On the one hand, the contained coordination anions have a planar structure, which is easy to pile up into columns, and electrons can conduct in the stacked columns, and the materials constructed from this can exhibit semiconductor properties, metallic properties, and even superconducting ...
