英文摘要	Two dinuclear dysprosium complexes with the Dy(III) ions bridged by the neutral bipyrimidine (BPYM) ligand were synthesized and magnetically characterized. They crystallized in a monoclinic and triclinic crystal system, respectively, with almost the same structural core, only differing in the lattice solvent molecules. Alternating current (ac) susceptibility measurements revealed that they exhibit significant slow relaxation of magnetization until 25 K in the absence of a dc field. The single and double relaxation processes were assigned to one and two types of Dy(III) environments in the two dimmers, respectively, with barriers of 266 and 345 K under zero field conditions. The magnetic hysteresis loops of 1 and 2 were both observed up to 2.5 K.; NSFC [21290171, 21321001, 21372014, 21441007, 21102039, 21572048]; BJSFC [2122023]; National Basic Research Program of China [2013CB933401, 2010CB934601]; BNLMS [20140108]; Educational Commission of Heilongjiang Province [1254G045, 12541639]; SCI(E); EI; PubMed; ARTICLE; wangbw@pku.edu.cn; gaosong@pku.edu.cn; 21; 8790-8794; 45
