Description
Summary:	[Display omitted] •A {Zn2Dy} single-ion magnet (SIM) with octahedral coordination geometry (Oh) was characterized.•The blocking temperature (TB) of this complex was 4.1 K based on FC-ZFC measurement.•The dominant relaxation process at high temperature region was Orbach process.•The effective barrier (Ueff) was 324 K for zero field whereas 565 K for 1000 Oe dc field. A {Zn2Dy} single-ion magnet (SIM) with octahedral coordination geometry (Oh) was synthesized and characterized. The zero-field-cooled (ZFC) and field-cooled (FC) magnetic susceptibility measurement diverged below 4.1 K, revealing the presence of the magnetic blocking. Combining experimental data and ab initio calculations, we depicted the dynamic relaxation characters of this complex in detail.
