A simple Co(II) mononuclear complex [Co(PPh3)2(NCS)2] has been studied in details. Its crystal and molecular structure is reported along with its IR a UV–Vis spectra. The DC magnetization studies confirm a sizable zero-field splitting D/hc?=??9.4?cm?1that is also confirmed by quantum-chemical calculations. The AC susceptibility data shows that there is a slow magnetic relaxation with two relaxation branches. The low-frequency branch occurs at about f?=?1–10?Hz and it tends to disappear progressively on heating. The high-frequency branch exists at the frequency ranges above f?>?200?Hz and this is shifted above the hardware limit (1500?Hz) on heating. The characteristics of this field-induced single molecule magnet strongly depend upon the applied DC field (0.2–0.4?T).
