Abstract

Herein, we report the synthesis and magnetic properties of the Co(II) coordination compound with the 1,1′-bis(1-((pyrid-2-ylmethylene)hydrazono)ethyl)ferrocene (L) ligand, having the general formula [CoLCl2]. The static magnetic data analysis supported by the CASSCF/NEVPT2 calculations revealed the presence of the triaxial magnetic anisotropy with Dexp = +35.2 cm−1 and large rhombicity (E/D = 0.31) in this complex (Dcalc = +34.5 cm−1, E/Dcalc = 0.30). The dynamic magnetic data confirm that the complex shows a slow field-induced (HDC = 1000 Oe) magnetic relaxation behaviour.
