摘要：

A helix chain Dy3+ compound, [Dy(HNA)(NA)(2)(NO3)](n) (1, HNA = nicotinic acid), was synthesized under solvothermal conditions and fully characterized. The absolute configurations of the enantiomers in P6(1) and P6(5) space groups are characterized by single crystal X-ray diffraction and circular dichroism (CD). Magnetic studies reveal that compound 1 exhibits ferromagnetic interaction and slow magnetic relaxation at low temperatures with the energy barrier of 37 K under 900 Oe dc field.
