Pressure-dependent isomerization: Pressure has been applied to manipulate the structure–property relationship of the copper(II)-based coordination network CuF2(H2O)2(pyz) (pyz=pyrazine). The elongated Jahn–Teller axis was found to switch sequentially from the NCuN (<0.9 GPa), to the OCuO (0.9–3.1 GPa), to the FCuF bonds (>3.1 GPa; see picture). This orbital reordering leads to a drastic change in the magnetic properties, whereby the magnetic structure changes from two-dimensional to one-dimensional above 0.9 GPa.
