Cobalt(II) Single-Ion Magnet Coordinated by Double Deprotonation of 2,2'-Bipyridine-6,6'-diol Ligands.

ABSTRACT: In this study, we synthesized a new Co(II) complex, [NMe₄]₂[Co(bpyO₂)₂] (1), using deprotonated 2,2'-bipyridine-6,6'-diol ligands (bpyO₂ ^2-). This compound exhibits a significant zero-field splitting (D) value. The far-infrared magneto spectroscopy and high-frequency and field electron paramagnetic resonance (HFEPR) measurements indicated that compound 1 possesses D = -54.8 cm^-1 and E ∼ 0 cm^-1. These findings were subsequently confirmed by other experimental data, including DC magnetic susceptibilities and variable temperature and variable magnetic field reduced magnetizations. Additionally, we conducted a series of AC magnetic susceptibility measurements to investigat
