Abstract
We report the thermal- and pressure-induced spin-crossover (SCO) in the
Co(II) imide complex [CoII(dpzca)2] using magnetic susceptibility
measurements and high-pressure Raman spectroscopy. This complex displays
thermally-induced reversible, complete, abrupt and hysteretic SCO, with T1/2↓
= 168 K upon cooling and T1/2↑ = 179 K upon heating with a thermal
hysteresis of ~11K and a pressure-induced reversible high spin (HS) ⇄ low
spin (LS) transition at ~0.3 GPa at room temperature.
