Gd-Co-triazole nitroxide free radical supramolecular one-dimensional chain complex and preparation method thereof

The invention discloses a Gd-Co-triazole nitroxide free radical supramolecular one-dimensional chain complex and a preparation method thereof, and relates to the technical field of heterospinning molecular material preparation. The preparation method comprises the following steps: adding Co (hfac) 2 * 2H2O and Gd (hfac) 3 * 2H2O in a molar ratio of 1: 1 into a container, slowly adding an n-heptane solvent into the container, and heating and stirring for reaction to form a mixed solution; then adding a dichloromethane solution of a nitroxide free radical ligand NITPh-triazole which is equal to the dichloromethane solution of the nitroxide free radical ligand NITPh-triazole in mole into the mixed solution; continuously heating and reacting for a while, and cooling to room temperature to form a purple solution; and filtering the purple solution into a small beaker with a flat bottom, sealing the opening of the beaker with a fresh-keeping film, standing in a humid environment with the temperature of 0-5 DEG C, an
