Tuning slow magnetic relaxation behaviour in a {Dy₂}-based one-dimensional chain via crystal field perturbation.

ABSTRACT: Two novel {Dy₂}-based one dimensional chain compounds {[Dy₂(H₃L)₄(OAc)₆]·2MeOH} _n (1) and {[Dy₂(H₃L)₄(OAc)₄(NCS)₂]·2MeOH} _n (2) (H₃L = 1,3-bis(2-hydroxynaphthalenemethyleneamino)-propan-2-ol) have been prepared under solvothermal conditions. Crystal structure analyses indicate that 1 and 2 feature similar 1D chain structures bearing dinuclear secondary building units. The difference between these two structures is that one chelated acetate ligand of Dy(iii) ion in 1 is replaced by one monodentate coordinated NCS^- ion in 2, leading to their different coordination numbers and geometry configurations to Dy(iii) ion.
