A novel salen type dinuclear dysprosium complex e.g., [Dy-2(H2L)(acac)(6)]center dot 4CH(3)OH (1) [H2L = N,N '-(1.3-propylene)bis(3-methoxysalicylideneimine) has been isolated by reactions of Dy(acac)(3)center dot H2O (acac = acetylacetonate) with salen type (H2L), respectively. X-ray crystallographic analyses reveal that asymmetric Dy(III) ions for 1 was bridged by one ligand displaying bicapped trigonal prism coordination geometry. Magnetic measurement shows that complex I exhibit slow relaxations under zero dc field. The presence of two magnetic relaxations in complex 1 is associated with the presence of minute differences in bond lengths around Dy(III) center. (C) 2016 Elsevier B.V. All rights reserved.
