A five-coordinate mononuclear Dy(III) complex with a C4v geometry was designed and synthesized. The complex exhibits a large anisotropy barrier in the absence of a dc magnetic field, which is attributed to the strong interaction between the phenolate and Dy(III) ion. Ab initio calculations suggest that the most likely relaxation pathway occurs through the second excited state. The terminal SMe group offers the potential for deposition on the Au surface through a strong Au-S bond.
A five-coordinate mononuclear Dy(III) complex with a C4v geometry (square-pyramid), [Dy(X)(DBP)2(TMG(H))2] [X = 3-(methylthio)-1-propoxide, DBP = 2,6-di-tert-butylphenoxide, and TMG(H) = 1,1,3,3-tetramethylguanidine] (1), was designed and synthesized. The complex displays a large anisotropy barrier of 432 cm-1 in the absence of a dc magnetic field benefiting from the strong interaction between the phenolate and Dy(III) ion. Ab initio calculations reveal that the most possible relaxation pathway is going through the second excited state. The terminal SMe group in the apical position furnishes the possibility of depositing it on the Au surface by the strong Au-S bond.
