title: Auxiliary ligand field dominated single-molecule magnets of a series of indole-derivative β-diketone mononuclear Dy(iii) complexes.
abstract: A series of four indole-derivative β-diketone mononuclear dysprosium complexes, namely, Dy(EIFD)3(bpy)·CH3CN (), Dy(EIFD)3(phen)·CH2Cl2 (), Dy(EIFD)3(dpq)·CH2Cl2 (), and Dy(EIFD)3(dppz)·2H2O () (EIFD = 1-(1-ethyl-1H-indol-3-yl)-4,4,4-trifluorobutane-1,3-dione, bpy = 2,2'-bipyridine, phen = 1,10-phenanthroline, dpq = dipyrazine[2,3-f:2',3'-h]quinoxaline, dppz = dipyrido[3,2-a:2',3'-c]phenazine) have been isolated by reactions of EIFD, DyCl3·6H2O and a series of auxiliary ligands. X-ray crystallographic analysis reveals that complexes are all eight-coordinated mononuclear structures. Magnetic studies indicate that complexes are all single-molecule magnets. Notably, the auxiliary ligands play an essential role in regulating their magnetism. The corresponding structural and magnetic parameters have been discussed in detail.
