Abstract

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 N-Cu-N (<0.9-GPa), to the O-Cu-O (0.9-3.1-GPa), to the F-Cu-F 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.
