specific Embodiment approach 1
[0020] Embodiment 1: This embodiment is a hexanuclear dysprosium cluster cyclic complex single-molecule magnet whose chemical formula is [Dy 6 (H 2 shi) 6 (2-pyca - ) 12 ], the molecular formula is C 114 H 90 Dy 6 N 18 O 42 ; The hexanuclear dysprosium cluster ring complex single-molecule magnet belongs to the monoclinic crystal system, P21 / c space group, and the unit cell parameters are: a=14.52, b=18.11, α=90°, β=104.07°, γ=90°;
[0021] This embodiment [Dy 6 (H 2 shi)6 (2-pyca - ) 12 ] in H 2 shi is salicylic hydroxamic acid that has lost a proton, 2-pyca is pyridine-2-carboxylic acid, and the structural formula of salicylic hydroxamic acid is The structural formula of pyridine-2-carboxylic acid is
specific Embodiment approach 2
[0022] Specific embodiment 2: This embodiment is: a preparation method of a hexanuclear dysprosium cluster ring complex single-molecule magnet is completed according to the following steps:
[0023] The salicylic hydroxamic acid, pyridine-2-carboxylic acid and Dy(NO 3 ) 3 ·6H 2 O is dissolved in the solvent, and ultrasonicated until the solution is clear to obtain a mixed solution A; in the solution A, salicylic hydroxamic acid, pyridine-2-carboxylic acid and Dy(NO 3 ) 3 ·6H 2 The molar ratio of O is 1:2:1; the volume ratio of the mass of salicylic hydroxamic acid to the solvent in the solution A is (0.0011g~0.0013g): 1mL; the mixed solution A is heated and refluxed for 1h under stirring conditions ~2h, the temperature of heating and refluxing reaction is 90 ℃ ~ 100 ℃ to obtain solution B; pyridine is added to solution B cooled to room temperature, and then heating and refluxing reaction under stirring conditions is 10min ~ 20min, the temperature of heating and refluxing r...
specific Embodiment approach 3
[0026] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the solvent is a mixture of methanol and acetonitrile, and the volume ratio of methanol and acetonitrile is 1:3. Other steps are the same as in the first or second embodiment.
