Abstract
The self-assembly of tetranuclear dysprosium based on triangular Dy3 system by using 5-(4-methoxybenzylidene)-8-hydroxylquinoline (HL) and 1,3-diphenyl-1,3-propanedione (dppd) afford a new compound [Dy4(μ3-OH)2L6(dppd)4]·2CH3CN (1). It was structurally and magnetically characterized. The results indicate that the four Dy ions is of typical rhombus topology and weak ferromagnetic interactions exists between adjacent Dy3+ ions. Additionally, it also displays slow magnetic relaxation behavior with energy barrier Ueff of 62.36K.
