Pressure-driven orbital reordering in the quantum magnet [CuF2(H2O)(2)(pyz)], (pyz = pyrazine), dramatically affects its magnetic exchange interactions. The crystal chemistry of this system is enriched with a new phase above 3 GPa, surprisingly concomitant with other polymorphs. Moreover, we discovered an unprecedented compound with a different stoichiometry, [(CuF2(H2O)(2))(2)(pyz)], featuring magnetic bi-layers.
